--- Comment #3 from Chris Wilson <chris at chris-wilson.co.uk> ---
Note to self: the wait is referencing an active pipe, with a range within the
plane. DERRMR seems set correctly.

Hmm, the vsync region is right up to the last scanline (give or take the
granularity). Do you see the error if you move the window off the bottom of the
screen?

Also the error state is reporting GPU page faults from the context and VT'd. A
recent drm-intel-nightly kernel should fix the context fault, and can you try
intel_iommu=off?

Do you see the same error on older kernels?
