--- Comment #3 from e.swanson+xorgbugs at alloscomp.com ---
To add my two cents:

I had this same issue on Arch Linux's 3.14.5-1-ARCH, Linus's v3.15, and
linux-3.15.y from the linux-stable tree. imirkin's advice of trying out
drm-next (commit bc1dfff04a5d4064ba0db1fab13f84ab4f333d2b) seems to have fixed
it for me.

I'm using an active (USB powered) DisplayPort -> Dual Link DVI adapter to drive
a 27" 2560x1440 monitor from a Lenovo ThinkPad W530. I don't have a dock.

As another data point, drm-fixes from airlied's tree (commit
884d6147ba19640a40fb45efe64360cdf92cac27) built but did not boot for me - it
hung before starting anything on my root drive (initrd seems to have loaded
fine).
