Commen= t # 2 on bug 10473= 1 from Christian K=C3= =B6nig 
Works as designed.

On older hardware generations the UVD firmware just stops all processing wh=
en
it finds an invalid stream.

The driver is then responsible to reset the UVD block with a specific reset
procedure to get it working again.

Unfortunately this reset procedure never made it through IP review and so
wasn't released to the public.

The only other option is a full ASIC reset which is implemented, but doesn't
works so well.
