1. Yes, one monitor connected with DP. There was an Nvidia card in there that
is supposed to be used later for virtualized compute, but for debugging
purposes, I took it completely out.

2. I'll try drm-tip later and post an update.

3. On the bisected git, I did

git bisect reset bisect/bad && git checkout HEAD~1

With this code, the screen comes up again.

4. I'll post the dmesg on the working build of 4.14.3+

5. The machine is booting to a login getty. There's no custom xorg.conf for X
