this is 2.6.26-rc4, i didnt test any earlier versions so far
(ok, i did test some pre -rc4 git versions i think 4 days
ago, but they also showed the problem) this is the
first time that i enabled CONFIG_SECURITY on my testbox.

I am currently trying to reproduce this with SLAB as Vegard
suggested for the kmemcheck report. After this I'll retest this
on a fresh tree to make sure it isnt something buggy on my part
and try some older kernels.

Greetings, Eric
