''So i did a "make clean" and a "make" (not a make
-j3 as i use to do) and recompiled 2.6.25-rc3 and now it works again.
Case closed under strange error.''
...

Although I don't think this would cause the error, it would be nice if Thomas could verify that the -j3 did not cause the problem.
I still cannot *believe* this bug, but i just checked out the latest kernel and did a make distclean and a make (with mr. bunks patch applied) and there it is again:

$ 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?
- ...?
