When waking up system from suspend
( triggered systemctl suspend ), I see only these logs on black screen:

when I press F2 everything disapears, otherwise no response to keys, Ctrl+Alt+F doesn't work

Lately I tried to make bluetooth dongle work with HSP headphones, but this happens even when dongle is deatached and it happens more frequently now. 3 times today. I'm on Ubuntu 20.04. It might be more frequent when suspend time are bigger. Another times when it wakes properly I see some logs before desktop shows only for a fraction of a second. Is this problem with snd_hda_intel?
