[Bug 946899] Re: 8086:2a02 [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung

 

Folks, I'm on HP ProBook 6360b, and I've experienced this issue on
Ubuntu 13.04 every day. I've switched my kernel to 3.11.6 from saucy,
and problem had gone. It works good with 13.04, I had uptime of about a
month.

➜  ~  uname -a
Linux comp_name 3.11.6-031106-generic #201310181453 SMP Fri Oct 18 18:54:15 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Exact image name is "linux-
image-3.11.6-031106-generic_3.11.6-031106.201310181453_amd64.deb"

Good luck!

  Since upgrading to 12.04 beta, I've seen this happen twice. The

  At that point I have to reboot to get my display back. In syslog, i
  see:
