Hit this when connecting a computer to an access point with a zydas usb
dongle using the zd1211rw driver. This seems entirely reproducible
(2/2). The system hit the BUG over night. I already sent this to
zd1211-devs and Ulrich Kunitz suggested that it might be a bug in
softmac, so resending to a wider audience.
