$ git describe
v2.6.25-rc6-14-gbde4f8f

As i already wrote: I tried to bisect this behavior, but with no result.

And Stefan didn't change anything in the involved drivers. I have no 
idea what could cause this kind of bug!
Suggestions?

- Maybe my build chain produces corrupted code?
- Maybe an udev error?
- ...?
