--- Comment #9 from Chris Wilson <chris at chris-wilson.co.uk> ---
I was hoping for just a little more information from the stacktraces. The most
obvious cause for the GTT reads would be the DRI2 copies, but having that
confirmed would have been useful. However, those cannot be eliminated due to
the API constraints. So other than working around the broken hw, we also need
to prevent the false positive EIO - which should be fixed in v3.9.
