i run MATE desktop on bookworm/sid (but it is mostly
testing packages with just a few more recent things that
i follow).
pretty much the same trouble i had for a while and no
further information have i been able to gather.
https://lists.debian.org/debian-user/2022/03/msg00233.html
i made sure i was using the most recent firmware packages
i could find plus i've had quite a few package updates come
through and have also been running the most recent kernel i
could get ahold of - so far no lock ups since then, but i
could not tell you which of my actions helped or if i'll
get a lock up again.
