Can you explain a bit more what that message is about?
I am encountering it in a completely different context
(PPP over ISDN) and I would like to know where to start
looking for the cause and developing a fix. The thread
on linux.kernel.wireless.general only seems to address
the specific situation in the wireless stack.
