Using Ubuntu 6.5.0-2.2 kernel as it is most likely to write the journal
after a lockup, I turned on some audio debug and saw this:
cold boot (all entries below have the same timestamp)
jammy kernel: snd_sof_intel_hda:hda_codec_probe: sof-audio-pci-intel-tgl
:00:1f.3: HDA codec #0 probed
I tested before rebooting by using the following commands:
sudo rmmod snd_sof_pci_intel_tgl
sudo rmmod snd_sof_intel_hda_common
sudo rmmod snd_hda_intel
sudo rmmod snd_intel_dspcfg
sudo modprobe snd_intel_dspcfg dsp_driver=1
sudo modprobe snd_sof_intel_hda_common
sudo modprobe
The legacy flag only works when you also set a model, for me the model
dell-headset-multi works. You have to shutdown the system completely
after setting these options. When you have done that you should be able
to reboot without locking up. The logs will still contain errors though.

i tried setting snd_intel_dspcfg.dsp_driver to 1 (legacy) as a
workaround without success but it did change the lockup output:
watchdog: BUG: soft lockup - CPU#7 stuck for 23s! [kworker/7:3:326]

No apologies neccesary, this is exactly how a community should work. I
will take a look at the issue you posted.

Title:
Apologies for hijacking this bug:
Executenor, would you mind taking a look at bug 2025040 and letting me
know if you've seen the same thing on your HP.
No pressure, tks.

I happen to have Lunar partition available (on an external SSD).
I booted Lunar on the same HP laptop and then did a restart/warmboot.
The trace is slightly different again so I've uploaded in case it helps.

I can also confirm that this problem indeed happens on a warm boot. A
cold boot seems to boot fine. I forgot to mention that. When i use the
5.15 kernel i had the same snd_hda_core call trace Brett posted. So yes
we are talking about the same issue but 6.5 handles it somewhat
different.

i am also seeing soft lockups related to snd_hda-core - also on a HP
15s-fq4xxx. My trace is different but it would seem too much of a
coincidence for the issues not to related.
This has been a day 0 problem for me. Changing kernels does not seem to
help. I have found that it occurs every time
Another interesting fact is that the system works fine if i use the
liquorix 6.4 kernel and switch the audio driver to legacy mode with
dsp_driver=1 together with setting the model to dell-headset-multi.
