[Intel-gfx] Possible 4.5 i915 Skylake regression

[Cyril Yab]

Hello,

I have the same laptop and the same issue, which still happens as of
today's Linus' tree.

A couple of additional details: for me, I don't need to suspend my
system to have the flashes appear (they do immediately after boot).
Also, setting i915.enable_rc6=0 solves the issue.

I've tried bisecting on drivers/gpu/drm/i915/ but I must have failed
somehow, as it blamed a trivial commit (drm/i195: Rename
gt_irq_handler variable).
