This commit doesn't help to fix this issue.
Comment 7 Jani Nikula 2014-09-15 11:03:46 UTC 
Please reverse bisect from fixes to nightly to see which commit fixes the issue.
Comment 8 Jani Nikula 2014-09-17 15:10:36 UTC 
Disregard that please. We won't queue bsw fixes to drm-intel-fixes, and we'll settle for having fixed this in nightly. Thanks.
