netconsole module unload broken between 2.6.19 and 2.6.20 (and still broken as of 2.6.21-rc6)

(Please CC me on emails, I'm not on LKML). Somewhere between 2.6.19 and 2.6.20, unloading of the netconsole module got broken. It's still broken as of 2.6.21-rc6. If you try to unload the module, the rmmod/modprobe-r just sits there forever. I can reproduce it on tg3, forcedeth and e1000
