Ah yeah that makes more sense. Can you try to bisect this? If you don't know a solid baseline commit just try latest 4.0-rc git and if that's good use that as the bisect starting point. That way you only need to bisect the i915 commits on top for 4.1, which isn't all that much. If that doesn't work go back in the rc release tags until you find something working. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
