Lenovo has released a firmware update for the docking station.
Please see:

Firmware update:

Unfortunately, there is no version for Linux. So you have to run Windows to
update the firmware. Is someone here running a dual boot environment who could
give it a try? Hopefully, this update solves our problem.
