Okay I take that back, I got my EL6 kernel rock stable with the correct blend of backported bits. So ignore that backtrace, however I did get another IOMMU hang on my upstream kernel with gem_linear_blits, so this should be fine to merge but I'm guessing we have more debugging to do on the VT-d cases.
