--- Comment #36 from Chris Wilson <chris at chris-wilson.co.uk> ---
The failure is reasonably consistent, it looks like the execlists
context-switch goes awry, and for whatever reason the guc is more susceptible.
It is more likely to be something not quite right in the interrupt routing upon
resume (first guess).
