Hello,
I have an IBM wifi card that has an Atheros chipset that was working perfectly 
with the madwifi driver untill the update that happened recently, now it is a 
big mess.
When I plug it in or at boot if it is plugged in when coldplugging pnp devices 
I got somethig like:

if I try to connect I get:

 # /etc/init.d/net.ath0 start
  * Starting ath0
  *   Bringing up ath0
  *     Configuration not set for ath0 - assuming dhcp
  *     dhcp
  *       ath0 does not exist

in some cases I just get: failed to connect.
Checking a bit more, ath0 doesn't exist, and I can't even see it on lspci.

When I unplug it, I get a kernel panic.

I am loading the modules:
ath_hal
wlan
wlan_acl
wlan_ccmp
wlan_tkip
wlan_wep
wlan_xauth
ath_rate_amrr
ath_rate_onoe
ath_pci
at boot thru /etc/modules.autoload.d/kernel-2.6.

Any ideas what is going on ? Am I doing something wrong ?

Thank you.
