Comment # 1 on bug 1190357 from Takashi Iwai

Could you give hwinfo output and dmesg output from the machine?
Also, check whether any trace of crash at the previous kernel logs in
/var/log/messages or whatever.

And, please try the latest kernel in OBS Kernel:stable repo, which is slightly
newer than 5.14.0.
Last but not least, if the problem persists with the latest kernel, please boot
with no_console_suspend, and check whether it shows anything interesting.
