<pre>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.</pre>
