Thats also what I suspect, just wanted to make sure.  I am using kernel
2.6.11-rc2 though, so I suppose it could still be possible there is some
faulty interaction in regards to the kernel version and hostap.  I'll
look into it more.  I am curious if the problem is that
pcmcia_request_io() gets called twice with the same client_handle_t
pointer.  Looking at the PCMCIA docs, it sounds as if a client handle is
bound to a particular PCMCIA socket, so it would seem there should be
two client handles then?  Anyways, thanks for the info.
	Best regards,
