Public bug reported:
This error occurred on my PC when booting Ubuntu from 22.04 in any
flavor, in Zorin and also with Pop!_OS 22.04.
Looks like a new kernel issue. It seems to me that it has to do with
Kernel 6.5, 6.8 +.
Should I be worried about this?
The problem does not occur in Fedora 39 or Debian 12.
