<6>[22661.140623] [drm] GPU HANG: ecode 0:0x85ffffbd, in texelFetch [12893],
reason: Ring hung, action: reset 
<6>[22661.140702] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace. 
<6>[22661.140707] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel 
<6>[22661.140709] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue. 
<6>[22661.140711] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

Reproduce steps:
1. xinit
2. bin/texelFetch offset gs isampler1DArray -fbo -auto
