--- Comment #2 from Chris Wilson <chris at chris-wilson.co.uk> ---
Note that we are holding a runtime wakeref for register access during parking,
and that our wakeref tracking is consistent -- it too believes that we haven't
released the runtime wakeref too early.

I dare say the third party (*cough* BIOS *cough*) that re-enabled VGA behind
our back also did so without device ownership leaving a MMIO_DEBUG fail behind.

Note that we never truly takeover from the BIOS here as i915.disable_displays=1
doesn't do what it says on the tin.
