No, the i915_error_state had everything I needed to see. It is the old
ddx bug that was hardcoding a maximum relocation address that never
corresponded with an actual hw limit. As soon we try to use memory above
that value, the GPU decides not to listen to us any more.

Fixed in xf86-video-intel 2.14.901
