Hi all,
kernel version:2.4.29
board :net4521
wireless card : Atheros-5212
diriver madwifi-cvs-current.tar.bz2(v 1.30 2005/02/22)
I built the customized image from 2.4.29 and booted from this image
The following sequence restarts the board
insmod wlan
insmod wlan_wep
insmod ath_rate-onoe
insmod ath_hal
insmod ath_pci xchanmode=0
ifup ath0
ifdown ath0
The board and Atheros work fine up to this point. After this once we give
the
command
ifup ath0
the system printed error message

Has any one faced this problem before?
What could be the possible cause?
Thanks in advance

According to the FAQ at http://www.mattfoster.clara.co.uk/madwifi-1.htm#2 ,
Madwifi is based on a binary-only module.

Yes, tainted by a proprietary licensed module. Sorry, lkml is not able
to help you with binary-only modules. Ask whoever supplied your driver
for support.

Next time run the oops through ksymoops. Undecoded oopses are almost
useless.
