It is already upstream reported and supposed to be fixed: https://bugs.freedesktop.org/show_bug.cgi?id=44510 Nevertheless both Factory and Tumbleweed are affected with their 3.3 kernel atm. Adding "intel_iommu=igfx_off" to the kernel boot parameters does help at least with Tumbleweed. I can't test it on Factory since X seem to have some other issues there and crashes shortly after start. Without this parameter using the PC is nearly impossible.
