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 0000:00:1f.3: HDA codec #0 probed OK: response: 10ec0236 jammy kernel: snd_sof_intel_hda:request_codec_module: hdaudio ehdaudio0D0: loading codec module: hdaudio:v10EC0236r00100002a01 jammy kernel: snd_sof_intel_hda:hda_codec_probe: sof-audio-pci-intel-tgl 0000:00:1f.3: HDA codec #2 probed OK: response: 80862812 jammy kernel: snd_sof_intel_hda:request_codec_module: hdaudio ehdaudio0D2: loading codec module: hdaudio:v80862812r00100000a01 warm boot jammy kernel: snd_sof_intel_hda:hda_codec_probe: sof-audio-pci-intel-tgl 0000:00:1f.3: HDA codec #0 probed OK: response: fe05 <then nothing for 26 sec until> jammy kernel: watchdog: BUG: soft lockup - CPU#2 stuck for 26s! [kworker/2:1:92] So it seems the HDA codec probe should return a PCI ID and for some reason after a warm boot it does not. -- 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/2027848 Title: Soft-lockup caused by snd_hda_intel Status in linux package in Ubuntu: Confirmed Bug description: I report this bug the the 6.5rc1 kernel.
