Created attachment 68623 [details] [review] Test patch.
VM is definitely enabled, otherwise you won't got that error in the first place.
Ok let's try to narrow down that bug a bit more, please apply the attached test patch and see what happens.
If the GPU hang vanished we indeed have a syncing issue, but not the PFP sync.
The patch resets the gpu constantly, even without X, with both linus git and agd5f drm-next-3.7 branch with mesa git.
