Removing libva didn't help. Lock ups still occur frequently.

A new symptom is that video doesn't need to be visible on the display
for the lockup to occur. -rc4 didn't improve the situation either.
Lockups are still instantaneous, I haven't had another one where the
gpu doesn't drag all the system.
