I was testing the stability of a madwifi-ng AP by having a client (also
madwifi-ng) do an iperf test using -t 100000.
I set the essid and mode 11g.
Somewhere inbetween, the AP will soft lock and only a hard reboot works.
A kernel dump appears (I took out all the addresses and numbers, too long
to type):

This is very reproducible.
This one above hung about 600secs into the iperf transfer.
Any thoughts, comments would be appreciated.
I have no idea where to start looking.
