--- Comment #4 from Mika Kuoppala <mika.kuoppala at intel.com> ---
Looking at the error state, the hardware never started to actually
execute the request on port[0], but it resting on a previous head/tail

Then we do a reset and and try to a recovery. And looks like the recovery will
find the port[0] to be empty. Which might indicate that that port request was
finally processed by hw.

Reproducing this with drm-tip might give us better error state.
