[Madwifi-users] oops

[Dan <da...@en...>]

Hi all.

I just set up a Linux box for a friend. He's got a Netgear WG311 card.
I used Gentoo's portage to install the madwifi driver ( compiled against 
2.6.11 ), and loaded the ath_pci module. I then ran:

iwconfig ath0 essid Draytec

This command worked fine. However, when I did:

ifconfig ath0 192.168.0.10

the PC restarted. I tried another couple of times and got the same 
results - the time between running ifconfig and the computer restarting 
sometimes varied, but I wouldn't get more than 20 seconds after running 
ifconfig. I could run iwconfig and sit there for *ages* without any issues.

I brought the card back home and put it in my computer and got slightly 
different results. I used the same driver ( different kernel though - 
2.6.10-nitro4 ). After modprobing the ath_pci module, iwconfig showed 
that the card had already found the ( ad-hoc ) network. But after 
running ifconfig, I got a kernel oops. I then sat there copying it out 
for the next 15 minutes.

I then rebooted into Windows XP and installed the latest Netgear drivers 
and the PC's been running fine for 20 minutes or so.

The kernel oops:
