ndis0 panic when ifconfig inet IP address

I have just upgraded my Asus A2 notebook from 6.1 to FreeBSD 7.0-RELEASE
#0 by doing a full clean install. (completely repartitioned my disc
prior to installing)

This notebook uses the Broadcom bcmwl5 wireless drivers which worked
faultlessly using ndis on 6.1

I can kldload ndis and driver bcmwl5_sys without a problem. 

However the system panics anytime that I try to config the ip address
either through rc.conf or directly e.g. ifconfig ndis inet

Got the error on the GENERIC kernel plus my own built kernel

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x0
fault code = supervisor read, page not present
instructor pointer = 0x20:0xc0a464f8
stack pointer = 0x28:0xcbfd8b04
frame pointer = 0x28:0xcbfd8b3c
code segment = base 0x0, limit 0xfffff, type 0xib
	     = DPL0, pres 1 def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 994 (ndis0 taskq)
trap number = 12

Any idea what the problem may be?
