I installed the supposed latest version of the driver (dmesg shows "i915 1.6.0
20150522") using intel-graphics-installer-linux from
https://01.org/linuxgraphics/downloads/intel-graphics-installer-linux-1.2.1

However, this still occurs. It happened just now while using GIMP.

The version I have installed is from May, so I think this
(https://bugs.freedesktop.org/show_bug.cgi?id=90814#c3) does not fix it.


I'm on a desktop with Lubuntu 15.10 (64 bit, kernel 4.2.0-22-generic).

[ 4785.816790] [drm] GPU HANG: ecode 3:0:0x2b0fffc7, in Xorg [972], reason:
Ring hung, action: reset
[ 4785.816794] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 4785.816797] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 4785.816800] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 4785.816802] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
