Which version of the Broadcom driver is this? Is the driver (mainly,
wl.o and the user space tool wl) available somewhere for downloading?

It looks like 4-way handshake was successful and the client was able to
decrypt Group Key msg 1/2.

Client side seemed happy..

..but AP deauthenticated/disassociated..
This could be because of the AP not liking something in the Group Key
msg 2/2.. Which version of madwifi driver are you using? If I remember
correctly, madwifi did not encrypt group key messages at some point. Has
that been fixed in the version you are using? It's possible that the
newer version of Broadcom driver started verifying that the Group Key
messages are encrypted..
