Found this error from weekend stress test in LNLM_RVP_HDA.

The command to reproduce: TPLG=/lib/firmware/intel/sof-ipc4-tplg/sof-hda-generic-ace1-4ch.tplg MODEL=LNLM_RVP_HDA SOF_TEST_INTERVAL=5 ~/sof-test/test-case/check-suspend-resume-with-audio.sh -l 100 -m playback

The error message is this,

I don't remember this error lately, reproduction rate will be very low.

dmesg is not available @fredoh9 ?

fredoh9 commented 4 months ago

right, dmesg was not captured in this case. I'm looking at the issue logs are not collected in some failure cases also.

I will use journalctl and upload equivalent dmesg when I have the access to the device.
