No matter what kernel version I run in the 3.13.* series the system will lockup after a day or so with the above error. Today it locked up at 9:09am CST - Mar 1 09:09:00 localhost kernel: [182499.820012] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... render ring idle. Again with the black screen and mouse cursor only. Cannot get to a log-in screen with CTRL-ALT-F1, CTRL-ALT-BKSPACE or with CTRL-ALT-ESC. And again, all background processes continue running as if nothing is happening. The current kernel version being run is - 3.13.0-46-generic #76-Ubuntu SMP Thu Feb 26 18:52:13 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
