[Markus <chickenmarkus@xxxxxxxxxx>]

I have that message with a HP EliteBook 850 G2 and docking station under
kernel 3.19.0-49-generic on Xubuntu 14.04. I think it causes an issue
with unrecognised external monitor.  I have attached the syslog while
reproducing via following steps:

0. directly after boot: external display is not recognised even it's connected to connected docking station (USB works fine)
1. disconnect docking station (line 1)
1. connect docking station (line 7)
2. activate external display (line 788)
3. deactivate external display (1407)
4. external display is not recognised again (USB works fine)

Maybe this is helpfull for fixing.
