Yeah that one is busted unfortunately. I've just pushed out a new -nightly
with an updated patch from Maarten:

commit c363376d3d5586c1e99f92969a7a7baf179206d7
Author: Maarten Lankhorst <maarten.lankhorst@xxxxxxxxxxxxxxx>
Date:   Mon May 11 10:45:15 2015 +0200

    drm/i915: Always keep crtc_state->active in sync with enable

How does that one fare?
-Daniel
