Christian,

Did you by chance boot with the dock "plugged in"?  Or was this the result of 
plugging in after boot?

There is a known issue that Mika is tracking regarding some problems with
Thunderbolt devices plugged in at boot.  It causes a few things to explode
down the line too (which I suspect is what happened).

Thanks,

Hi,

Dock was plugged in after boot. I included another dmesg output,
where I marked the time point that I plugged the device in.

Good to know.
