Black cursor

After booting the drm-intel-nightly (2014-03-14) on a Haswell with fastboot=1
the cursor is all black (see attachment). After a while the system stops
responding for a few seconds and starts spitting out warnings (see dmesg).

Doing a suspend/resume brings back the normal cursor and all is fine. I'm
having trouble bisecting this since I get hit by the EDP_FORCE_VDD regression
and have to suspend/resume in order to see anything at all.

The problem is present at b3064154dfd37deb386b1e459c54e1ca2460b3d5
where the EDP_FORCE_VDD bit (and my screen) is back.

I can bisect this by adding the EDP_FORCE_VDD fix on top of every bisect but I
would be happy if I can get a pointer to possible suspects first.

Thanks
