I've tried with 3.17.2 and have similar results. I got no BUGs during
boot and even:
Console: switching to colour frame buffer device 240x67

If I disconnect the laptop from docking station X starts, but then
connecting it back (while X is running) gives [1] and xrandr -q shows
only eDP1 (i.e. the built in laptop display).
So the bug seems to be present in 3.17 as well.
