--- Comment #1 from Jordan Justen <jljusten at gmail.com> ---
This should be fixed by the kernel commit:

commit 7b9748cb513a6bef4af87b79f0da3ff7e8b56cd8
Author: Jordan Justen <jordan.l.justen at intel.com>

    drm/i915: Add GEN7_GPGPU_DISPATCHDIMX/Y/Z to the register whitelist

which is currently in:

  drm-intel/drm-intel-next
  drm-intel/drm-intel-next-fixes
  drm-intel/drm-intel-next-queued
  drm-intel/drm-intel-nightly
  drm-intel/drm-intel-testing
  drm-intel/for-linux-next

The symptom can be hidden by disabling the command parser:

echo "0" | sudo tee /sys/module/i915/parameters/enable_cmd_parser

Or, on the kernel command line:

i915.enable_cmd_parser=0
