As mentioned in the linked bug [1], I bisected it to:

drm/i915: Use cpu relocations if the object is in the GTT but not mappable
Iirc your issue goes away with rc6=0, the residual bugs we still have all still happen with rc6 disable, so probably something else. Hence also why we're asking everyone who can still reproduce to try a bisect, since with rc6 disabled we've can't reproduce the hang any more (beforehand we could reproduce it on 3 different ilk machines). The important part is to not enable rc6 (on ironlake at least) when bisecting. -Daniel
