--- Comment #3 from Chris Wilson <chris at chris-wilson.co.uk> ---
The render ring is off in a world of its own, flying through space, blt, bsd,
vebox all coincidentally wrapped at exactly the same time with just before the
breadcrumb for idling on suspend - and on all 3 rings it parsed the MI_FLUSH_DW
command but did not execute the seqno write. Otherwise they look solid, all the
pointers (acthd, faddr, ring start match). Oh my.
