[Kernel-packages] [Bug 2105421] [NEW] nct6687 not available in Ubuntu 24.10

[Ar Rakin]

Public bug reported:

Hello there,

I have a system with MSI PRO Z790-A MAX WIFI motherboard. I need the
nct6687 kernel module to monitor the sensors of the system, but the
kernel that's packaged for Ubuntu 24.10 does not seem to include
nct6687. I built it myself and installed it from
, however I got secure boot
errors when loading the module into the kernel: "Key was rejected by
service".

I do not want to disable secure boot, is there a specific package/kernel
update that I can install to fix this?

Bug description:
  [Impact]

  Qualcomm's graphic driver does not work because necessary firmware
  files are missing in Ubuntu's linux-firmware package.

  An example error:

   [  200.275893] adreno 3d0.gpu: [drm:adreno_zap_shader_load [msm]]

  [Fix]

  Import necessary firmware files from the upstream linux-firmware
  project.

  [Test Case]

  Install Ubuntu on the Qualcomm boards such as RB3G2, RB8, boards.
  Run a simple rendoring program such as 'kmscube'.

  [Where problems could occur]

  When we support the graphics driver (drivers/gpu/drm/msm/) for
  Qualcomm IoT platforms (https://ubuntu.com/download/qualcomm-iot).

[Kernel-packages] [Bug 1876632] Re: [nvidia] Corrupted/missing textures when switching users, switching VTs or resuming from suspend

[Julien Olivier]

The note in the summary is not quite correct: "And even then, only
desktops that use suspend/resume and VT switching may trigger it, if
ever."

In my case, it happens after any suspend / resume cycle, without ever
switching VT (or user).

Bug description:
  [Impact]

  The Nvidia driver corrupts and/or forgets its textures when resuming
  from suspend, by design. Documented here:

  
https://www.khronos.org/registry/OpenGL/extensions/NV/NV_robustness_video_memory_purge.txt

  *NOTE* that this is actually not a common problem because the system
  must be using Nvidia as the primary GPU to be affected. So generally
  only desktop users will encounter the bug, not laptops. And even then,
  only desktops that use suspend/resume and VT switching may trigger it,
  if ever. Even in development the bug cannot be reproduced reliably.

  [Workarounds]

  * Always log into a Xorg session and if corruption occurs then type:
  Alt+F2, R, Enter

  *

  [Test Plan]

  [Where problems could occur]

  [Original Bug Report]

  I recently installed ubuntu 20.04 on my computer, and I am running
  into an issue when I do the following:

  * Login with a user on desktop
  * Select switch user, and login as second user
  * Switch user again, and return to original user

  At this point, text and icons in the menubar / sidebar are corrupted.
  Text and icons in normal windows appear correctly. I have attached a
  screenshot of what this looks like.

[Kernel-packages] [Bug 2105421] Re: nct6687 not available in Ubuntu 24.10

[Daniel Letzeisen]

The kernel does have nct6683 module which supports nct6687, though the
voltage readings are not accurate. If you prefer the nct6687 module, it
would really help if they upstreamed it to kernel, but I don't see much
effort there: https://github.com/Fred78290/nct6687d/issues/52

If you want to sign your own kernel module:

[Kernel-packages] [Bug 2092363] Re: Missing (but referenced) SOF firmware in pc-kernel – No Audio

[Jürg Häfliger]

The pc-kernel snap is basically a repackaging of the kernel Debian
package plus some additional things like firmware blobs. If a firmware
is not explicitly referenced by the kernel (listed in the output of
'modinfo ') it will not be included in the snap.

For the record, the snap repos are here:

Bug description:
  I am encountering an issue with the pc-kernel snap on my HP EliteBook
  840 G11 laptop running Ubuntu 24.04.1 LTS with the new TPM+FDE
  feature. Despite testing multiple kernel channels, the system fails to
  detect any audio devices. However, when booting into a live session of
  Ubuntu 24.04.1 LTS, audio functions as expected. This suggests the
  issue may be related to the pc-kernel snap.

  Right now I'm on channel 24/stable (version: 6.8.0-50.51), but I have
  tried 24-hwe/stable and 24.10/stable as well.

  For reference, I have first tried to seek help in the support section over at 
Ubuntu Discourse, and I was encouraged to file a bug report here against the 
linux package on Discourse:

[Kernel-packages] [Bug 1876632] Re: [nvidia] Corrupted/missing textures when switching users, switching VTs or resuming from suspend

[Daniel van Vugt]

** Tags added: oracular

** Changed in: nvidia-graphics-drivers-470 (Ubuntu)
   Status: Triaged => Won't Fix

** Description changed:

  [Impact]
  
  The Nvidia driver corrupts and/or forgets its textures when resuming
  from suspend, by design. Documented here:
  
  
https://www.khronos.org/registry/OpenGL/extensions/NV/NV_robustness_video_memory_purge.txt
- 
- Although it's so awkward to implement everywhere that realistically
- compositors will never support it fully. Instead we're waiting for an
- Nvidia driver fix.
  
  *NOTE* that this is actually not a common problem because the system
  must be using Nvidia as the primary GPU to be affected. So generally
  only desktop users will encounter the bug, not laptops. And even then,
  only desktops that use suspend/resume and VT switching may trigger it,
  if ever. Even in development the bug cannot be reproduced reliably.
  
  [Workarounds]
  
  * Always log into a Xorg session and if corruption occurs then type:
  Alt+F2, R, Enter
  
  *
  
https://download.nvidia.com/XFree86/Linux-x86_64/510.54/README/powermanagement.html#PreserveAllVide719f0
  
  [Test Plan]
  
  [Where problems could occur]
  
  [Original Bug Report]
  
  I recently installed ubuntu 20.04 on my computer, and I am running into
  an issue when I do the following:
  
  * Login with a user on desktop
  * Select switch user, and login as second user
  * Switch user again, and return to original user
  
  At this point, text and icons in the menubar / sidebar are corrupted.
  Text and icons in normal windows appear correctly. I have attached a
  screenshot of what this looks like.

Bug description:
  [ Impact ]

  This introduces support for the ACP70/ACP71 audio co-processors, as
  well as soundwire related integration. The main patchesets are:

  1. [PATCH V3 00/25] ASoC: amd: Add support for ACP7.0 & ACP7.1 platforms[1]
  2. [PATCH V4 0/6] soundwire: amd: code improvements and new platform 
support[2]
  3. [PATCH] ASoC: amd: ps: use switch statements for acp pci revision id 
check[3]

  As well as their dependent patches.

  [ Test ]

  1. Test record/playback of built-in mic and speakers by, say, recording and 
playing the speaker test sound in the gnome control center.
  2. Connect to headphones and test playback and recording.
  3. Suspend the machine and test 1. and 2. again.
  4. Test the above 3 on a ACP63 machine.

  [ Where the problems could occur ]

  Most of the codes are AMD-specific. However, those patches contain
  refactors to the existing ACP63 codes. Errors in those refactoring may
  impact existing ACP63 platforms.

  The patch "[PATCH V3 19/25] ASoC: amd: ps: update file description and
  copyright year"[3] didn't get backported, because it conflicted due to
  the recent MODULE_IMPORT_NS() API change in cdd30ebb1b9f (module:
  Convert symbol namespace to string literal). This patch only change
  the module description and doesn't have real functional impact, so was
  not pulled in.

[Kernel-packages] [Bug 1876632] Re: [nvidia] Corrupted/missing textures when switching users, switching VTs or resuming from suspend

[Daniel van Vugt]

Thanks for pointing that out. I've now corrected the text:

- suspend/resume and VT switching
+ suspend/resume or VT switching

** Description changed:

  [Impact]
  
  The Nvidia driver corrupts and/or forgets its textures when resuming
  from suspend, by design. Documented here:
  
  
https://www.khronos.org/registry/OpenGL/extensions/NV/NV_robustness_video_memory_purge.txt
  
  *NOTE* that this is actually not a common problem because the system
  must be using Nvidia as the primary GPU to be affected. So generally
  only desktop users will encounter the bug, not laptops. And even then,
- only desktops that use suspend/resume and VT switching may trigger it,
- if ever. Even in development the bug cannot be reproduced reliably.
+ only desktops that use suspend/resume or VT switching may trigger it, if
+ ever. Even in development the bug cannot be reproduced reliably.
  
  [Workarounds]
  
  * Always log into a Xorg session and if corruption occurs then type:
  Alt+F2, R, Enter
  
  *

  [Test Plan]
  
  [Where problems could occur]
  
  [Original Bug Report]
  
  I recently installed ubuntu 20.04 on my computer, and I am running into
  an issue when I do the following:
  
  * Login with a user on desktop
  * Select switch user, and login as second user
  * Switch user again, and return to original user
  
  At this point, text and icons in the menubar / sidebar are corrupted.
  Text and icons in normal windows appear correctly. I have attached a
  screenshot of what this looks like.

  BT hardware is not available on certain machines:

  1. Machine with MT7925 BT (USB VID/PID 13d3/3628)
  2. Machine with MT7925 BT (USB VID/PID 0489/e14e)

  [Fix]
  Add USB device IDs into device table in btusb.c fixes the issue.

  1. For VID/PID 13d3/3628, the patch has already been merged into
  linux-next:

  f597b8982d51 Bluetooth: btusb: Add new VID/PID 13d3/3628 for MT7925

  2. For VID/PID 0489/e14e, the patch is still under review. Out of the
  urgency, we're going to make a SAUCE patch first.

  
  [Test Plan]
  1. Install Ubuntu image and boot into the OS
  2. Run $ sudo checkbox-cli run 
com.canonical.certification::bluetooth/detect-output and see if the test is 
passed

  [Where problems could occur]
  The two BT hardware may have not yet been matured, so there might be issues 
in the future.

Title:
  [rtw89_8852ce] Resume from suspend fails with "xtal si not ready" and
  "mac init fail"

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  *1. Problem Overview:**

  WiFi connection fails after resuming from suspend (suspend-to-RAM /
  S3). The adapter is visible but does not scan for networks and cannot
  connect. WiFi functionality is only restored after a complete shutdown
  (cold boot); a simple reboot (warm boot) is not sufficient.

  **2. Affected Hardware:**

  * Laptop: Legion Pro 5 16ARX8 - Type 82WM - Model 82WM00ERUS
  * WiFi Card: Realtek RTL8852CE PCIe 802.11ax Wireless Network Controller
  * Identifiers (from lspci): [10ec:c852], Subsystem: [17aa:5852]
  * Driver in use: rtw89_8852ce

  **3. Affected Software:**

  * Distribution: Ubuntu 24.04.2 LTS (noble)
  * Current Kernel: 6.11.0-21-generic (problem also occurred with OEM kernel 
6.11.0-1017-oem)

  **4. Steps to Reproduce:**

  1.  Boot the system normally. WiFi connects and works correctly.
  2.  Suspend the system (e.g., via menu option or closing the lid).
  3.  Wait a few seconds.
  4.  Resume the system (e.g., open the lid or press the power button).

  **5. Expected Result:**

  WiFi should reconnect automatically or, at minimum, scan and display
  available networks, allowing manual connection.

  **6. Actual Result:**

  The WiFi icon might be present, but no networks are detected or displayed. 
Connection attempts fail. NetworkManager cannot initialize the interface 
correctly.
  The `sudo dmesg` command after resume shows repeating errors similar to:
 `rtw89_8852ce :03:00.0: xtal si not ready(W): offset=90 val=10 mask=10`
 `rtw89_8852ce :03:00.0: mac init fail, ret:-110`

  **7. Troubleshooting Attempts (Unsuccessful):**

  * Disabled "Fast Startup" in Windows 11 (dual boot setup).
  * Disabled WiFi power saving via NetworkManager (`wifi.powersave = 2`).
  * Reinstalled the `linux-firmware` package.
  * Tested the standard HWE (`-generic`) kernel instead of the OEM kernel.
  * Tested the `rtw89_core.disable_aspm=Y` module parameter.
  * Verified that BIOS/UEFI is up-to-date (checked via Windows).
  * Manually reloading the kernel modules (`sudo modprobe -r rtw89_8852ce 
rtw89_pci rtw89_core` followed by `sudo modprobe rtw89_8852ce`) after resuming 
also fails to restore WiFi functionality.

[Kernel-packages] [Bug 2092158] Re: [SRU] With certain configs (such as with NVIDIA GPU driver), Bluetooth HSP/HFP profile may be missing after suspend/resume

[Yao Wei]

On oracular with bluez 5.77.0-ubuntu2 with a unit with NVIDIA GPU with
Jabra Speak2 55 UC, this issue is reproducible.  Updating to -proposed
(5.77.0-ubuntu2.1), this issue is still reproducible, considering it
validation failed.

(p.s. this issue cannot be reproduced with AirPods Pro 2, probably the
device will try reconnecting HSP/HFP profile when it is not connected)

Bug description:
  [ Impact ]

   * On system with NVIDIA proprietary driver and Bluetooth interface,
  when connecting to a Bluetooth headset, after doing a round of
  suspend/resume, A2DP interface would be reconnected, but not HSP/HFP.

   * This fix is suggested by upstream by reconnecting HSP/HFP (if not
  connected) when A2DP is connected.

  [ Test Plan ]

   * Find a system where NVIDIA proprietary driver is installed.

   * Connect it to a Bluetooth headset and see whether the above issue
  is reproducible.

   * Update bluez from -proposed, see whether HSP/HFP is available and
  after switching to HSP/HFP, mic and headphone are both working.

  [ Where problems could occur ]

   * The changed part would mainly affect the connection of Bluetooth
  headset.  If the fix brings regression, it would affect the connection
  and reconnection of Bluetooth devices.

  [ Original issue ]

  We found that with certain hardware configs, such as whether NVIDIA
  GPU is/is not available (but not always), can affect HSP/HFP profile
  after suspend/resume.  We will post debug information later on
  affected configs.

  [Reproducible Steps]
  1. Connect Bluetooth headphones
  2. Check that Bluetooth Handsfree is available in Sound settings
  3. Suspend the system and wake it up

  [Expected Behavior]
  Bluetooth Handsfree profile should be available after automatic reconnection

  [Actual Behavior]
  Bluetooth Handsfree profile is missing, one way to make it unreproducible on 
the system in question is to use prime-select to switch to Intel GPU:
    sudo prime-select intel

[Kernel-packages] [Bug 2092158] Re: [SRU] With certain configs (such as with NVIDIA GPU driver), Bluetooth HSP/HFP profile may be missing after suspend/resume

[Yao Wei]

On noble with bluez 5.72.0-0ubuntu5 with a unit with NVIDIA GPU,
connected to Jabra Speak2 55 UC Bluetooth speaker, this issue is
reproducible. Updating to -proposed (5.72.0-ubuntu5.2), this issue is
still reproducible, considering it validation failed.

Bug description:
  [ Impact ]

   * On system with NVIDIA proprietary driver and Bluetooth interface,
  when connecting to a Bluetooth headset, after doing a round of
  suspend/resume, A2DP interface would be reconnected, but not HSP/HFP.

   * This fix is suggested by upstream by reconnecting HSP/HFP (if not
  connected) when A2DP is connected.

  [ Test Plan ]

   * Find a system where NVIDIA proprietary driver is installed.

   * Connect it to a Bluetooth headset and see whether the above issue
  is reproducible.

   * Update bluez from -proposed, see whether HSP/HFP is available and
  after switching to HSP/HFP, mic and headphone are both working.

  [ Where problems could occur ]

   * The changed part would mainly affect the connection of Bluetooth
  headset.  If the fix brings regression, it would affect the connection
  and reconnection of Bluetooth devices.

  [ Original issue ]

  We found that with certain hardware configs, such as whether NVIDIA
  GPU is/is not available (but not always), can affect HSP/HFP profile
  after suspend/resume.  We will post debug information later on
  affected configs.

  [Reproducible Steps]
  1. Connect Bluetooth headphones
  2. Check that Bluetooth Handsfree is available in Sound settings
  3. Suspend the system and wake it up

  [Expected Behavior]
  Bluetooth Handsfree profile should be available after automatic reconnection

  [Actual Behavior]
  Bluetooth Handsfree profile is missing, one way to make it unreproducible on 
the system in question is to use prime-select to switch to Intel GPU:
    sudo prime-select intel

Bug description:
  == linux ==

  [Impact]

  This patch series introduce soundwire support for AMD platform, as
  well as code reorganization in preparation for that.

  [Fix]
  Backport the AMD SoF driver from kernel 6.12 and its sdw_utils for dependency

  == alsa-ucm-conf ==
  [Impact]

  This patch series introduce soundwire support for AMD platform. The
  audio function won't work if no proper driver and alsa-ucm-conf
  installed.

  [Fix]
  Backport the patches from 
https://github.com/alsa-project/alsa-ucm-conf/pull/470 to support AMD SoF 
driver.

  [Test]

  1. Install the test kernel
  2. Install proper alsa-ucm-confs
  3. Confirm the audio function normally on the DUT with 1) AMD soundwire and 
2) existing Intel platforms using soundwire. Might include:

  * Checkbox audio test plan
  * Built-in speaker and built-in mic
  * Audio function when headphone is connected to the DUT.

  [Where problems could occur]

  Patches needed, other than 3 SAUCE patches that planned to upstream in
  6.13 cycle, are listed in [1] to [8] below.

  Soundwire used to appear mostly on Intel platforms and is almost
  always in combination with sof. To support AMD, it has to be
  refactored into a more generic framework (or at least that's what AMD
  people did).  This happens in patch series [1][2] and [3], extracting
  soundwire code from the sound/soc/intel directory to a more generic
  location, as well as rename/refactor things to better fit the ASoC
  context. This will impact all other soundwire platforms and if not
  done correctly, regression risk may be high.

  The all other patch sets other than [5] are AMD specific, so
  theoretically the impact is limited to AMD platforms with soundwire,
  which are rather uncommon.

[Kernel-packages] [Bug 2104321] Re: [rtw89_8852ce] Resume from suspend fails with "xtal si not ready" and "mac init fail"

[Chris Chiu]

Thank you for reporting this and helping make Ubuntu better. Could you
please boot into a Ubuntu kernel (not third party kernel) and execute
the following command only once, as it will automatically gather
debugging information, in a terminal:

$ apport-collect 2104321

Title:
  [rtw89_8852ce] Resume from suspend fails with "xtal si not ready" and
  "mac init fail"

Status in linux package in Ubuntu:
  New

Bug description:
  *1. Problem Overview:**

  WiFi connection fails after resuming from suspend (suspend-to-RAM /
  S3). The adapter is visible but does not scan for networks and cannot
  connect. WiFi functionality is only restored after a complete shutdown
  (cold boot); a simple reboot (warm boot) is not sufficient.

  **2. Affected Hardware:**

  * Laptop: Legion Pro 5 16ARX8 - Type 82WM - Model 82WM00ERUS
  * WiFi Card: Realtek RTL8852CE PCIe 802.11ax Wireless Network Controller
  * Identifiers (from lspci): [10ec:c852], Subsystem: [17aa:5852]
  * Driver in use: rtw89_8852ce

  **3. Affected Software:**

  * Distribution: Ubuntu 24.04.2 LTS (noble)
  * Current Kernel: 6.11.0-21-generic (problem also occurred with OEM kernel 
6.11.0-1017-oem)

  **4. Steps to Reproduce:**

  1.  Boot the system normally. WiFi connects and works correctly.
  2.  Suspend the system (e.g., via menu option or closing the lid).
  3.  Wait a few seconds.
  4.  Resume the system (e.g., open the lid or press the power button).

  **5. Expected Result:**

  WiFi should reconnect automatically or, at minimum, scan and display
  available networks, allowing manual connection.

  **6. Actual Result:**

  The WiFi icon might be present, but no networks are detected or displayed. 
Connection attempts fail. NetworkManager cannot initialize the interface 
correctly.
  The `sudo dmesg` command after resume shows repeating errors similar to:
 `rtw89_8852ce :03:00.0: xtal si not ready(W): offset=90 val=10 mask=10`
 `rtw89_8852ce :03:00.0: mac init fail, ret:-110`

  **7. Troubleshooting Attempts (Unsuccessful):**

  * Disabled "Fast Startup" in Windows 11 (dual boot setup).
  * Disabled WiFi power saving via NetworkManager (`wifi.powersave = 2`).
  * Reinstalled the `linux-firmware` package.
  * Tested the standard HWE (`-generic`) kernel instead of the OEM kernel.
  * Tested the `rtw89_core.disable_aspm=Y` module parameter.
  * Verified that BIOS/UEFI is up-to-date (checked via Windows).
  * Manually reloading the kernel modules (`sudo modprobe -r rtw89_8852ce 
rtw89_pci rtw89_core` followed by `sudo modprobe rtw89_8852ce`) after resuming 
also fails to restore WiFi functionality.

  Build failure when CONFIG_NET_SWITCHDEV=n due to CVE-2024-26837 fix
  backport

Status in linux package in Ubuntu:
  New
Status in linux source package in Jammy:
  In Progress

Bug description:
  [ Impact ]

  Since jammy:linux commit 0158242f01a0 ("net: bridge: switchdev: Skip
  MDB replays of deferred events on offload"), the kernel build fails
  when CONFIG_NET_SWITCHDEV=n, as observed in e.g. jammy:linux-kvm. The
  error is as follows:

    /build/jammy/net/bridge/br_mdb.c: In function 'br_mdb_queue_one':
    /build/jammy/net/bridge/br_mdb.c:640:13: error: implicit declaration of 
function
    'switchdev_port_obj_act_is_deferred'; did you mean 
'switchdev_port_obj_add'? [-Werror=implicit- function-declaration]
  640 | switchdev_port_obj_act_is_deferred(dev, action, 
&mdb.obj)) {
  | ^~
  | switchdev_port_obj_add

  [ Fix ]

  Add a dummy implementation of switchdev_port_obj_act_is_deferred() for
  the CONFIG_NET_SWITCHDEV=n case. This approach was chosen because it
  is less risky and also requires minimal changes compared to the
  alternatives:

  * Backport 9776457c784f ("net: bridge: mdb: move all switchdev logic to 
br_switchdev.c"), which would involve resolving significant conflicts, or
  * Revert the CVE fix, cherry-pick nearly all prerequisite patches from [1] 
and [2], and then reapply the CVE fix.

  Note that register_switchdev_blocking_notifier() does nothing when
  CONFIG_NET_SWITCHDEV=n. Therefore, nbp_switchdev_(un)sync_objs (the
  sole caller of br_mdb_replay()) does not run in the first place.

  [ Test Plan ]

  Compile test with both CONFIG_NET_SWITCHDEV=y and
  CONFIG_NET_SWITCHDEV=n.

  [ Where problems could occur ]

  Any regressions caused by this tiny fix-the-fix patch should be caught
  during compilation.
