kernel messages 3.16 git (stripped)

nouveau/linux-2.6 branch linux-3.17
(I have honestly no idea anyore which branch one should follow/test in the last months...)

* Laptop in ThinkPad dock, lid closed
* external monitor attached to DVI connector on dock
* suspend (from Gnome)
* resume
* external monitor gets no signal
* opening lid does nothing, have to take out the laptop and laptop LVDS activates
* putting back into dock gets in previous error state as after resume

I forgot to note, that IIRC the last stable version is my nouveau 3.12 git kernel which I keep around to keep my work system going.

With http://cgit.freedesktop.org/~darktama/nouveau/commit/?id=a68e95365a4248d3f58c8663e4513c79273ac704 (disp/nv50: fix dpms regression on certain boards) applied on top of http://cgit.freedesktop.org/~airlied/linux/log/?h=drm-next my DVI-connected monitor (via ThinkPad dock) enables after resume.
