<pre>gdg is not G45, its i915g. However, this bug should be specifically kept to the
expected error with gen6/gen7 (and at a push gen5, and/or gen8 with ringbuffer
*not* execlists).
gdg is unexpected (we have never observed it before on gen3 and believe the
seqno write and MI_USER_INTERRUPT is ordered) and the miss looks genuine. So
that probably relates to the use of the physical status page where we currently
do not mark as snooped (unlike all other platforms).</pre>
