I'm see panics like this one as well on multiple systems in lab (e.g. ProLiant SL390s G7, PowerEdge R805). Looks same to what Bruno reported here: https://lore.kernel.org/all/CA+QYu4rt2VHWzbOt-SegA9yABqC-D36PoqTZmy6DscWvp+6ZMQ@mail.gmail.com/
It started around 8d0749b4f83b - Merge tag 'drm-next-2022-01-07', running a bisect atm.
