> drm/i915/guc: Keep guc submission permanently engaged
>
> We make a decision at module load whether to use the GuC backend or not,
> but lose that setup across set-wedge. Currently, the guc doesn't
> override the engine->set_default_submission hook letting execlists sneak
> back in temporarily on unwedging leading to an unbalanced park/unpark.
>
> v2: Remove comment about switching back temporarily to execlists on
> guc_submission_disable(). We currently only call disable on shutdown,
> and plan to also call disable before suspend and reset, in which case we
> will either restore guc submission or mark the driver as wedged, making
> the reset back to execlists pointless.
> v3: Move reset.prepare across
>
> Fixes: 63572937cebf ("drm/i915/execlists: Flush pending preemption
> events during reset")
> Testcase: igt/drv_module_reload/basic-reload-inject

I would like to believe this solved it, but the evidence has started piling
up... It looks like this commit did not change anything :s
