This one is proving quite hard to nail down, I've been reading over the codepaths and can't spot the major problem with it. The code seq in these patches is a bit off in places, i.e. it removes scratch page stuff but then still needs it in the i915_remove_entries patch, so I've moved the bisection around a bit, but I can't get a DMAR error with the code prior to this AGP rework and I can after the patch above. I'll keep digging and hope one of you guys has a good idea.
