Not madpilot@ but my own amdgpu machine also gets bit by
dma_fence_wait_timeout(). While cinnamon and X both crash, only cinnamon is
reflected in dmesg:

drm-66-kmod was built on this src revision as part of my own mass rebuild after
your __FreeBSD_version bump.

The cinnamon backtrace leads to mesa, for which I will need to rebuild without
stripping so we get some symbols, if you want to see the userspace side of
things.
