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. -Daniel -- Daniel Vetter Mail: daniel@xxxxxxxx Mobile: +41 (0)79 365 57 48 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
