Thanks for your answers!

At the time I wrote the email I was too busy to do the kernel bisect
and needed a working pc. I did it now. (btw: it was introduced with
3.10.0... did a full bisect...)

Turns out the problem was introduced with a patch to the driver of my
tv card. This problem is thus "solved" by unplugging my tv card which I
rarely used anyways ;)

I submitted a bug report and hopefully someone who understands the
offending commit can create a fix:
https://bugzilla.kernel.org/show_bug.cgi?id=63551

cheers
