ANALYTICS:
-------------------
If you look at comment #31
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1269777/comments/31),
you will notice in dmesg.log (which I could safe at runntime to /tmp and
copy it over to another pc), that the freeze occurs right after taking
the system from the series 3 docking station.

According to an article about docking solutions in Think-Wiki, this might be a
problem with the hotplugging of this device and newer kernel series:

I am investigating in this!
