--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
As usual, Display B is nowhere near a Y-fence.

Interestingly though:

  05400000  4194304 40 40 0 0 P Y dirty uncached (fence: 5)

i.e. at the time of the error, the only Y-fenced surface is being accessed (it
is currently pinned for use in the hardware) which implies that we are
servicing i915_gem_fault(). Impression remains that this is the hardware crying
wolf.
