A bisect should sort it out pretty quickly, given that you've got working code in 3.0 and not-working code in 3.1-rc. You can start by manually bisecting across the 3.1 release candidates, and then narrow it down from there by bisecting only across the drivers/gpu/drm/i915 directory. -- keith.packard@intel.com
