I've been hit by this on a box for the last few months, quite often, on
kernel 4.0.1 (vanilla)

I am another reporter seeing the same problem, this time in
4.2.0-rc7-00071-g0bad909 with no kernel options for drm or i915, so
4.2-rc7 does not cure it.
I do not have dmesg with drm_debug yet, will see if I can reproduce it
at will (so fast I have seen it once).

Please try v4.2-rc7 or drm-intel-nightly branch of [1], drop all i915
module parameters (such as i915.enable_rc6 i915.enable_fbc
i915.lvds_downclock and i915.semaphores, they are not for regular use),
add drm.debug=14, attach dmesg all the way from early boot.

Same porblem on my box. I can reproduce this very often mostly using chromium.
My options for i915 driver: options i915 enable_rc6=7 enable_fbc=1
lvds_downclock=1 semaphores=1
My box is gentoo box with 4.1.2 kernel.
I had no such problems before 4.1.x kernel...

I never close the lid immediately after booting, so in my case that

So far I have not found a correlation between the intel drm flip error
and things I did. Sometimes the error occurs after an hour, sometimes
not for two days. Now it is even 5 days ago:
