I can confirm that this also affects Ubuntu 24.04 Noble's linux-hwe-7.0
kernel, via Linux Mint 22.1.
Hardware:
- Huawei MateBook 14 2024
- Intel Core Ultra 5 125H (Meteor Lake)
- Audio: sof-hda-dsp / sof-audio-pci-intel-mtl
- Two external ASUS monitors connected via HDMI/DisplayPort
Distribution:
- Linux Mint 22.1 (Ubuntu 24.04 base)
- PipeWire 1.0.5
Tested kernels:
- 7.0.0-30-generic
- 7.0.0-31-generic
The failure has occurred with both kernels.
I confirmed that the failure happens immediately after resume from system
suspend. The system is using s2idle:
$ cat /sys/power/mem_sleep
[s2idle] deep
At the failing resume:
09:54:22 kernel: PM: suspend exit
09:54:22 systemd-sleep: System returned from sleep operation 'suspend'
Immediately afterwards:
sof-audio-pci-intel-mtl 0000:00:1f.3:
sof_pcm_prepare: pcm0 (HDA Analog), dir 0:
failed to set hw_params after resume
The kernel also reports:
DSP panic!
error: DSP Firmware Oops
error: Exception Cause: AllocaCause
IPC timeout
IMR restore failed, trying to cold boot
timeout waiting for purge IPC done
Boot iteration failed: 3/3
error code: 0x2328
dsp init failed after 3 attempts with err: -110
Failed to start DSP
After this, playback and capture both stop working, including:
- internal speakers
- internal digital microphone
- HDMI/DisplayPort audio
ALSA still enumerates the devices and PipeWire/WirePlumber remain
running, but PipeWire receives ALSA timeouts. Restarting PipeWire,
WirePlumber or ALSA does not recover the DSP. A reboot restores audio.
One difference from the reproduction described in this issue is that I
have not yet confirmed that an active stream was using the internal
analog path at the exact moment of suspend. External HDMI/DP displays
were connected.
I reported my case upstream in thesofproject/sof#10955.
Peter Ujfalusi (contributor) confirmed that linux-stable did not pick commit
0c0e418dbcf0582bf80d8dbfd9b306607c065992 for 7.0.y because 7.0 is non-LTS, and
suggested that Ubuntu should pick the patch for its 7.0 kernel.
This therefore also appears to require the backport in Noble's linux-
hwe-7.0 package, not only the Ubuntu 26.04 kernel.
