GUC is disabled in the kernel by default so unless there were explicit
instructions for testing GUC I would keep it disabled for now, that is boot
without i915.enable_guc_submission=1. I haven't seen any problem booting w/o
this kernel parameter, if you do then that should be tracked on a separate
ticket.
