--- Comment #4 from Chris Wilson <chris at chris-wilson.co.uk> ---
My earlier statement was completely wrong, it definitely is acting as a single
4k at 60Hz stream. The bandwidth is right at the edge of the available clocks, and
it would seem we are not quite generous enough with our fifo allocation.
