Ditto with linux-image-5.8.0-2-amd64 5.8.10-1, except that I don't
have any log message about the crash. The machine suddenly rebooted.

This is apparently the same bug I had in the past:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=929308

In each time, the crash occurs just after a reboot that follows
a kernel upgrade. I have the impression that the nouveau driver
doesn't properly reset the video card (since the card keeps data
from the previous boot), and there might be some inconsistency
due to the kernel upgrade. Otherwise I wonder why this seems to
occur *only* after kernel upgrades.
