BUG when doing rmmod kafs, 2.6.28-rc9-wl-24896-gf4f5c96

Hello!

I wanted to play around with AFS and when trying to rmmod kafs
(to load openafs's libafs...), I get the attached bug.
I assume this is the same case for newer versions, just building
next-20090106 now.

Sincerly,

Nico

ps: as always, cc on reply me.
