Package: src:linux
Version: 5.4.8-1
Severity: grave
Justification: causes non-serious data loss
I have noted in the last days that sometime the desktop freeze from some
fraction of second to some seconds and then the desktop is usable again
without problems.
I have had a longer freeze, then I get a black screen with all blocked.
I have used the Magic Key Ctrl-AltGr-REISU, but I can only have the
keyboard leds working, Ctrl-Alt-Fx working, but I cannot reach a console
or the Desktop GUI, so I have done a Ctrl-AltGr-B to reboot.
After reboot, I see the following errors in the log:

Probably this is due because I have reboot the PC.
I have searched back to see if there are error for the previously
