--- Comment #2 from Chris Wilson <chris at chris-wilson.co.uk> ---
Junk loaded from context. The simplest theory for this is that the context gets
overwritten by another batch. Wildest speculation is that the hw reads the
wrong pages.

In the past we found that caching the context in L3 improved the mtbf, but it
did not completely eliminate this bug.

If you can please try a drm-intel-nightly, I believe it should contain more
error state information for debugging context issues.
