[Intel-gfx] [PATCH i-g-t v5 0/7] kms_flip_event_leak and kms_vblank fixes for

[Marius Vlad]

Hi,

I'm getting mixed results w/ this series applied. The kernel seems to
trip in different ways either from suspend or on reload (running the BAT
suite on a HSW machine), and though it seems totally
unrelated I can't reproduce the same behaviour without the series
applied. Haven't managed to get some valid output as the machine
dead-locks/freezes, so please be patient until I try to isolate the
problem. It could be I stumbled something totally unrelated.
