How about the dmesg? Can you try these? http://lists.freedesktop.org/archives/intel-gfx/2013-September/033966.html Oops wrong bug, ignore that last one. We've got a bunch of fixes queued up in drm-intel-nightly branch of [1] for BYT and DP etc. Please try that and attach dmesg with drm.debug=0xe if it doesn't work. Thanks.
