Hi Lucas,

When the hangcheck handler was replaced by the DRM scheduler timeout handling we dropped the forward progress check, as this might allow clients to hog the GPU for a long time with a big job.
It turns out that even reasonably well behaved clients like the Armada Xorg driver occasionally trip over the 500ms timeout. Bring back the forward progress check to get rid of the userspace regression.
We would still like to fix userspace to submit smaller batches if possible, but that is for another day.

Maybe you could add a Reported-by tag from Russell?
