Video froze last night, 01/17/2016 21:06:30 after uptime of 14d 12h 40m from the last video freeze. I was running kernel 3.19.0-42-generic #48~14.04.1-Ubuntu SMP Fri Dec 18 10:24:49 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux) at the time. This time the hangcheck error was noted in my syslog
Jan 17 21:17:32 localhost kernel: [1255120.808035] [drm:i915_hangcheck_elapsed [i915]] *ERROR* Hangcheck timer elapsed... render ring idle
I did a reboot via SSH from my tablet and loaded the newest 3.19 kernel
3.19.0-43-generic #49~14.04.1-Ubuntu SMP Thu Dec 31 15:44:49 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
As usual during these freezes the mouse cursor would move but all other actions are frozen. Could not switch to another desktop and so forth.
