--- Comment #1 from Arti Zirk <arti.zirk at gmail.com> ---
It seems like I managed to triger that same bug. I have a Intel i5-3317U with
HD4000 grapics.

I'm not running stock kernel and I have tainted my kernel by using some i915
options (i915.enable_rc6=7 i915.enable_fbc=1 i915.lvds_downclock=1
i915.fastboot=1) so it probably doesn't help much.
