kernel: [154858.820009] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed.

[Chris]

I'm hoping I can get some advice/help here on this list with the above
problem that is causing system lockups. I didn't want to post to the
main list as I'm not sure it would be appropriate, I'm not even sure
it's appropriate here but I'll give it a try. If someone has a better
list to post to please let me know.

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. At that time I can usually CTRL>ALT-F1 log in and
run 'sudo reboot' to restart the system.

Kernel version information is:

Linux version 3.13.0-43-generic (buildd at tipua) (gcc version 4.8.2
(Ubuntu 4.8.2-19ubuntu1) ) #72-Ubuntu SMP Mon Dec 8 19:35:06 UTC 2014
(Ubuntu 3.13.0-43.72-generic 3.13.11.11)

I'll be more than willing to submit any and all information anyone needs
to help me solve this. 

One reply I received to my bug report is that I need to update my bios
however I don't understand how that would solve the problem I'm having.

Thanks in advance for any and all replies/assistance.

Chris
