Hi Borislav, that's a known issue and should be fixed in the next rc, see this bugreport: https://bugs.freedesktop.org/show_bug.cgi?id=77009
You might also want to try my branch with 3.15 fixes which includes the necessary patch for this: http://cgit.freedesktop.org/~deathsimple/linux/log/?h=drm-fixes-3.15-wip Let me know if that branch works for you or not.
