Can you try out the for-chainsaw branch from

git://people.freedesktop.org/~danvet/drm

Afaics it seems to help here on my snb with VT-d enabled. But that means
it'll still crash eventually with tons of DMAR fault message (like yours).
But compared to previous kernels it now doesn't insta-die for me. So no
high hopes, please, but it would be interesting to know how this fares for
you.

Meanwhile I'll be trying a few other funky tricks.
