Afaikt this is just I quick hack and I intend to rip it out (same for the original entry from Carsten Emde). I've sent Carsten Emde a quick debug patch which should fix his issues for real, but unfortunately never got a test results for it. To test, please try this patch: https://bugs.freedesktop.org/attachment.cgi?id=65156 I've volunteered Jani from our team to write up a neat patch series to fix this issue for good (which should hopefully land in 3.7).
