I thought that buggy userspace shouldn't cause a complete GPU lockup like
this...
The kernel log says "GPU reset succeeded", but it leaves GNOME session
completely unusable (hung, artifacts on screen), restarting GDM also fails, the
only way to recover is rebooting (sometimes only through Sysrq)

And also I get a very similar lockup (the same messages in kernel log, again
with all kernel/firmware versions I tried) in a few Steam games running on
Proton/DXVK.

Will try different mesa versions
