Unfortunately, I don't have direct access to the affected hardware myself, so I'd have to prep a test build, hand it off to someone and play relay. I could do that, but it'd have some lag and possible multiple round-trips... Anyone inside Intel have hardware handy to test on? :p -- Jarod Wilson ja...@redhat.com
