--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
That looks entirely to be a test bug, intel_reg_read reading unknown registers
which is then caught by the kernel on its next mmio. Since the kernel is not
aware of a third party messing around with registers, it takes the blame upon
itself.
