I still remember that there was a similar problem found two years ago on the same hardware with similar broken screen output and it also crashed after Xorg was started, but I cannot confirm that they are the same problems. I don't know whether error messages are simliar. The old problem happens on Linux 3.7 ~ 3.10 with VT-d enabled. It only happened when not using Xen, so I added 'intel_iommu=off' to Linux boot arguments to workaround it.Hmm, do you see any chance in finding the commit which made it working again? Perhaps there was some workaround for this hardware which is missing in Xen now... After some tests, I found the information I provided before was incorrect. It seems the problem happens on all Linux >= 3.7, including Linux 4.0.5, so the old problem was never fixed. Here are some 'dmesg | grep -i iommu' outputs. Linux 3.6.11 with intel_iommu=on works fine.
