Just got an Atheros-based card from eBay, stuffed it into my Thinkpad
T23 (ignoring the complaints about two ethernet cards being installed)
and got myself this Oops:
BUG: unable to handle kernel NULL pointer dereference at virtual address
00000000
printing eip:
f0a3322d
*pde = 00000000

This Oopsed within NetworkManager but it also crashes/burns when
activated manually. Setting parameters with iwconfig does not bring it
down but ifconfig'ing it up does...
Card is known as 02:02.0 Ethernet controller: Atheros Communications,
Inc. AR2413 802.11bg NIC (rev 01), it is an Askey AR2413A (802.11b/g)
FCC ID:PPD-AR5BMB5 IC:4104A-AR5BMB5
Madwifi (with evil closed HAL code) works on the same card (with
somewhat weak reception which is annoying as I got an Atheros-based card
to get a better radio than the Broadcom-based ones I have lying
around...)
More info available on request...
Cheers//Frank
