The fix was reverting 2 commits wrt 'CP_MEC_DOORBELL_RANGE' and in kernel 5.10.61 there was another commit related to that, and I'd like to know if that caused a regression. I don't expect it, but it's better to verify. The symptom of bug 990312 were easy to detect with: cat /sys/class/drm/card0/device/gpu_busy_percent
