Those are two separate issues so please choose one of them for this bug to be about and open a new bug for the other.

done

[Daniel van Vugt (vanvugt)]

Thanks. Can you try booting an older kernel version (like the original 5.11.0-16.17) and tell us if that avoids the issue?

[Andrei Sergeev (aelsergeev)]

I've checked this kernel version 5.11.0-16.17 and it didn't fix the problem

[Daniel van Vugt (vanvugt)]

Please run this command in a terminal:

  uname -a

to verify you are really running 5.11.0-16.17

[Andrei Sergeev (aelsergeev)]

yes I did it when I was checking it

Shutdown the system, press power button for 15 seconds should fix it.
