Bug Description
I am doing some graphics development in Ubuntu 12.04 and I came across this bug today. I am just drawing a simple open gl program for drawing a quadrilateral. There are no issues when I am running the same program in different machine which uses an ATI radeon graphics card.
I am using Ubuntu 12.04
Using the 2:2.17.0-1ubuntu4 version of the xserver package.
My dmesg is showing the following messages everytime the freeze occurs
[ 84.384822] [drm:i915_
[ 84.384885] [drm] capturing error event; look for more information in /debug/
[ 84.401191] [drm:i915_
Update: I upgraded to kernel 3.5.0 and this bug has been fixed.
