There seems to be a netdevice refcounting (freeing) bug in mac80211.
I frequently see the "waiting for netdev to become free, refcount = 1"
message on rmmod. I don't remember the message text exactly, but I think you
know what I mean.
Is there any way I can debug this and find out who is leaking the resource?

Most probably it's this one:
http://bugzilla.kernel.org/show_bug.cgi?id=9778
There was a discussion on netdev about this. Not a mac80211 bug AFAIK.

Oh, yes. This might be possible. So let's see. It will soon be fixed then.
