Well that behavior could actually be completely normal, incorrectly feeding UVD
with informations can crash the block.

That can happen for example because of a corrupted video stream, or because the
userspace driver doesn't work 100% correctly.

Whatever it is the recommended way to handle it is to just reset the block and
that's exactly what we do, the only problem is that it's really hard to get the
reset to be 100% reliable.
