==Bug detailed description==
-----------------------------
I test it on drm-intel-nightly, drm-intel-fixes, drm-intel-next-queued,
drm-fixes, drm-next and core-stuff branch. It only happens on drm-intel-nightly
branch.
Test it on drm-intel-nightly/07d0c831d920, it works well.

output:
IGT-Version: 1.9-g25cf055 (i686) (Linux:
3.19.0-rc3_drm-intel-nightly_296cb8_20150108+ i686)
