That could be a Mesa issue, anyway it should probably be tracked separately from this report.

Created separate bug report https://bugs.freedesktop.org/show_bug.cgi?id=107152

(If that is a Mesa issue, no more than user processes / X11 should have crashed - but not the kernel amdgpu driver... right?)

Not exactly, MESA could create a bad request (faulty GPU address) which would lead to this. It can even be triggered on purpose using a debug flag from MESA.
