Please add drm.debug=0xe to your kernel command line, reproduce the bug again and attach full dmesg.

Hi Ander,

I reported this bug on https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1420290
As my updates there don't appear here, I'm posting here also.

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...

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.

*** Bug 90381 has been marked as a duplicate of this bug. ***

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).

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

os : Gentoo
motherboard: Core1333DVI-2.66G

Is this problem still appear in newer Kernel versions? if so please attach recent logs.
