Daneil's fix has not been applied which means the replicable system bug is out there in the wild, not addressed. Daniel's fix could have been applied and rolled out to all users in mainline and consequently stable. Instead another architectural level fix is still under discussion, which is of no value to end users whose systems can reset in the meantime. Its just not responsible behaviour. So I feel both of these drivers need to be marked as BROKEN unless/until a fix lands. I'm hoping the vidc team will come up with something else. --- bod
