I've got slab corruption when I use restricted key:

This is fully reproductible. I'm not sure whether it's a ieee80211softmac bug or a zd1211rw bug.

zd1211rw driver comes from http://dsd.object4.net/git/zd1211.git. .config and full dmesg can be downloaded from http://laurent.riffard.free.fr/2.6.18-mm2/. --
