--- Comment #60 from Chris Wilson <chris at chris-wilson.co.uk> ---
My current run is up to 12 days (25428 iterations) without incident on my
STK2mV64CC. That's has been the longest I've managed to leave it alone over the
last few weeks and not run other tests! I think this compute stick isn't
showing the symptoms. However, given the hypothesis that this is from poking at
the HW at the same time as it is powergating (or transitioning into a deep
rc6), it should have been only a matter of time for it to strike, given the
same hw and sw. Of course, I'd like to assume the reason I haven't seen it is
because it is unreproducible on drm-tip!
