--- Comment #2 from Lionel Landwerlin <lionel.g.landwerlin at linux.intel.com> ---
A probable guess is that your shader is taking too long to complete, so the
i915 driver declares that your workload has hung the GPU even though it's still
in process.
You can recompile your kernel with an adjusted value for
DRM_I915_HANGCHECK_PERIOD or disable the hangcheck by giving the
i915.enable_hangcheck=0 parameter on the kernel command line.

If that solves your problem, I'll reassign the issue to i915.
