<pre>Perhaps a little optimistic, but it looks very promising,
commit fa9a09f15065650d97e3b1336d11e4ad9672b759 (HEAD -> drm-intel-next-queued,

drm/i915/execlists: Clear STOP_RING bit on reset
During reset, we try to ensure no forward progress of the CS prior to
the reset by setting the STOP_RING bit in RING_MI_MODE. Since gen9, this
register is context saved and do we end up in the odd situation where we
save the STOP_RING bit and so try to stop the engine again immediately
upon resume. This is quite unexpected and causes us to complain about an
early CS completion event!
