--- Comment #2 from Chris Wilson <chris at chris-wilson.co.uk> ---
It didn't handle a context-switch interrupt and so the ELSP queue was drained
-- the hardware was idle, even though we still thought it was processing work.
Does this still happen on a recent kernel? There's a little more info in new
error states that may help to debug this problem.
