[Kernel-packages] [Bug 1752437]
Is anyone else seeing the issue where the touchscreen/pen don't work when the computer is first powered on (needs to be rebooted at least once)? If so, was this supposed to be fixed by this or should that be a separate bug report? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1752437 Title: [HP ENVY x360 - 15-bq102ng] Touchscreen does not work Status in linux: Fix Released Status in linux package in Ubuntu: Confirmed Bug description: The touch screen on my HP ENVY x360 15-bq102ng does not work with stock kernel or with mainline kernel 4.16-rc3. marc@snapbug:~$ xinput ⎡ Virtual core pointerid=2[master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4[slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=13 [slave pointer (2)] ⎣ Virtual core keyboard id=3[master keyboard (2)] ↳ Virtual core XTEST keyboard id=5[slave keyboard (3)] ↳ Power Buttonid=6[slave keyboard (3)] ↳ Video Bus id=7[slave keyboard (3)] ↳ Video Bus id=8[slave keyboard (3)] ↳ Power Buttonid=9[slave keyboard (3)] ↳ AT Translated Set 2 keyboardid=12 [slave keyboard (3)] ↳ HP Wireless hotkeys id=14 [slave keyboard (3)] ↳ HP WMI hotkeys id=15 [slave keyboard (3)] ↳ HP Wide Vision FHD Camera: HP I id=11 [slave keyboard (3)] ↳ HP Wide Vision FHD Camera: HP W id=10 [slave keyboard (3)] WORKAROUND: Use the following patch with 4.17-rc3: https://bugzilla.kernel.org/attachment.cgi?id=275381 ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: xorg 1:7.7+19ubuntu3 Uname: Linux 4.16.0-041600rc2-generic x86_64 ApportVersion: 2.20.7-0ubuntu3.7 Architecture: amd64 BootLog: No key available with this passphrase. /dev/mapper/nvme0n1p2_crypt: clean, 621596/15597568 files, 54013381/62389248 blocks CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Wed Feb 28 22:34:50 2018 DistUpgraded: Fresh install DistroCodename: artful DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Advanced Micro Devices, Inc.

Please find attached the output of "sudo lspci -vvv" for a 'good state'. The output for the bad state is empty. ** Attachment added: "sudo lspci -vvv (good state)" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2099935/+attachment/5862832/+files/lspci_vvv_good_state.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2099935 Title: PCI initialization failure following kernel panic reboot on Raspberry Pi CM4 Status in linux package in Ubuntu: Invalid Status in linux-raspi package in Ubuntu: Triaged Bug description: Ubuntu Server 24.10 Linux ubuntu 6.11.0-1004-raspi #4-Ubuntu SMP PREEMPT_DYNAMIC Fri Sep 27 22:25:34 UTC 2024 aarch64 aarch64 aarch64 GNU/Linux We're seeing that following a kernel panic and reboot, the PCI fails to initialize correctly and associated devices (such as Wi-Fi card) are not available. Issue Description: • On the first boot, everything works correctly. • However, after a Kernel Panic, the device reboots, but PCIe does not reset or re-initialize properly. • When this happens: o The Wi-Fi card is not recognized. o The lspci command shows no PCI devices. o The dmesg log includes the message: [0.591441] brcm-pcie fd50.pcie: link down • A soft reboot does not fix the issue. • The only way to recover is to completely remove and reconnect power (hard reboot). We have tried modifying /boot/firmware/config.txt and /boot/firmware/cmdline.txt, which has reduced but not fully resolved the issue. How to Reproduce The Problem: 1.Power up the hardware 2.Run ‘lspci’ – observe the result includes the PCI Bridge and Wi-Fi card 3.Trigger a kernel panic with the command ‘echo c | sudo tee /proc/sysrq-trigger’, causing a reboot 4.Run ‘lspci’ – observer the output is now empty The same issue does not occur on Raspberry Pi OS - it seems to be specific to Ubuntu.

[Kernel-packages] [Bug 2099935] Re: PCI initialization failure following kernel panic reboot on Raspberry Pi CM4
Yes, the problem exists with 6.8 (that's actually where we first noticed it was occurring). "operatingSystem": "Ubuntu 24.04 LTS" "kernel": "6.8.0-1019-raspi" One update to share is that the problem does also occur on Raspberry Pi OS as well (contrary to what I stated above). It also occurs ~50% of the time (I just got lucky when previously testing and got a string of successful tests). Given that it works ~50% of the time it might be some kind of race condition. I wonder if there are any ways to test delaying the pci initialization that can be applied via configuration? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2099935 Title: PCI initialization failure following kernel panic reboot on Raspberry Pi CM4 Status in linux package in Ubuntu: Invalid Status in linux-raspi package in Ubuntu: Triaged Bug description: Ubuntu Server 24.10 Linux ubuntu 6.11.0-1004-raspi #4-Ubuntu SMP PREEMPT_DYNAMIC Fri Sep 27 22:25:34 UTC 2024 aarch64 aarch64 aarch64 GNU/Linux We're seeing that following a kernel panic and reboot, the PCI fails to initialize correctly and associated devices (such as Wi-Fi card) are not available.

[Kernel-packages] [Bug 2099935] Re: PCI initialization failure following kernel panic reboot on Raspberry Pi CM4
Is it possible that the issue might be related to the hardware watchdog timer? I note the following lines in the dmesg output: [2.214004] bcm2835-wdt bcm2835-wdt: Broadcom BCM2835 watchdog timer [2.288820] watchdog: Delayed init of the lockup detector failed: -19 [2.295372] watchdog: Hard watchdog permanently disabled Is this expected output for a CM4? I've tried researching how to enable it but am a little out of my depth. cat /boot/config-$(uname -r) | grep BCM2835_WDT CONFIG_BCM2835_WDT=y This suggests the BCM2835 support is compiled into the kernel.
