Happens to me as well on 22.04.3 with 6.5.0-14-generic or 6.5.0-21-generic.

6.2.0-39 works fine.

Not completely sure whether this is an identical issue, but at the very least looks very similar, I was seeing:

UBSAN: array-index-out-of-bounds in /build/linux-hwe-6.5-q7NZ0T/linux-hwe-6.5-6.5.0/drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/vega10_processpptables.c:621:5

A workaround appears to have been found here: https://bugzilla.kernel.org/show_bug.cgi?id=201957#c94

Setting the kernel parameter amdgpu.mcbp=0 appears to have stopped the crashing for me.

amdgpu.mcbp=0

Does not work for me.
