Weird badness in 2.6.0-test2

Hi,

Attached is a log of some oops I received when shutting down my laptop using HostAP kernel modules for my wireless card in kernel 2.6.0-test2-mm2. Is this a known problem?

Thanks,
Josh

Should be fixed in Linus's latest tree.

Still in test2-mm4, but not sure if that's recent enough :)
