Why yes, yes I am :) How did you know? ;)

Yep, that reproduced it. Well, not exactly like that. Instead of a hardlock
I had a totally unstable system afterwards: X crashing, not being able
to start it up again, shells not starting up when trying to log in at
a console, after a while no console switching possible.

However, I have no idea how to solve this problem. Is it a fault of the
kernel? Or a fault of my screwed system? If the second, any suggestions
how I could fix it?
