DRM-Tip kernels on Skylake from commit 8e6dfee and onwards
(drm-tip: 2017y-01m-05d-16h-48m-32s UTC integration manifest)
get into infinite suspend with following options turned on:
i915.enable_guc_submission=1 i915.enable_guc_loading=1

With this patch the testhost i6700K survived dozen rounds of
igt@gem_exec_suspend@basic-s3, without it the first run hangs the 
machine.

Tested-by: Tomi Sarvela <tomi.p.sarvela@intel.com>

Best regards,

Tomi Sarvela
