--- Comment #31 from Dmitry Nezhevenko <dion at dion.org.ua> ---
It looks like I'm experiencing almost same behavior with Lenovo t440p machine
and UltraDock on kernel 3.17.

The different thing is that I'm not getting any docked connectors in xrandr if
I dock laptop on-the-fly. While xorg.log shows followed:

After restarting Xorg, everything seems to be ok until I unplug it.
