System is Ubuntu 14.04.1 LTS with kernel 3.13.0-43-generic, I have noticed the lockups periodically since 09/13/2014. I can't remember what kernel version was in use then possibly kernel 3.13.0-35-generic or -36.
It has continued periodically through versions -39; -40 and now to -43. The last time this has happened was Dec 13 14:40:57 localhost kernel: [154858.820009] [drm:i915_hangcheck_elapsed] ERROR Hangcheck timer elapsed... render ring idle.
At times when it locks up I will have a cursor on a black screen and will have to press the power button to restart other times it will lockup whenever I'm in an application such as Firefox or Evolution. At that time I can usually CTRL>ALT-F1 log in and run sudo reboot to restart the system.
Some information that I've posted to Ubuntu Pastebin - Output of lshw -C video
