--- Comment #4 from Ralf-Peter Rohbeck <RalfPeter.Rohbeck@quantum.com> ---
Resolution to the mystery: It seems that I had changed /etc/default/grub before
today's testing but not run update-grub. When I installed the 3.13-0.bpo.1
kernel the kernel command lines were fixed.

What caused the original failure were the explicit mode settings I had on the
kernel command line, namely "video=DP-1:2560x1440-24@60e
video=DP-2:2560x1440-24@60e video=DVI-0:2560x1440-24@60e". I had to add those
settings in the past (see https://bugs.freedesktop.org/show_bug.cgi?id=72167.)
Without them settings it works.

I'll attach some kern.logs - there all sorts of interesting things going on
that are apparently needed to get the DP outputs up and running with my DP->DVI
converters. Setting the resolutions explicitly keeps those interesting things
from happening.
