Subject: [gentoo-user] problem with kernel and net-wireless/linux-wlan-ng

Hello, Group,

I am trying to install and use NetGear MA111 usb wireless network. I
followed the instructions here:
http://gentoo-wiki.com/HOWTO_Prism2_USB_on_Gentoo


But I get errors when I try to install the kernel module.
linux-wlan-ng-0.2.8 # modprobe prism2_usb prism2_doreset=1
WARNING: Error inserting p80211 (/lib/modules/2.6.19-gentoo-r5/linux-
wlan-ng/p80211.ko): Invalid module format
FATAL: Error inserting prism2_usb (/lib/modules/2.6.19-gentoo-r5/linux-
wlan-ng/prism2_usb.ko): Invalid module format

My system is built with gentoo 2007.0 livecd for i386 system. Here
is uname -a
Linux map 2.6.19-gentoo-r5 #1 SMP Wed Apr 4 05:44:43 UTC 2007 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

Initially, my /usr/src/linux -> linux-2.6.19-gentoo-r5, and it's not
configured or compiled, so I don't have .config or include/linux/
version.h files that linux-wlan-ng-0.2.8 looks for.

I created a simple config (has wireless support, usb support),
compiled it but never installed it. So I have .config and include/
linux/version.h files. linux-wlan-ng could compile but the result
kernel modules cannot be installed unless forced:

modprobe -f prism2_usb prism2_doreset=1
Segmentation fault
map # lsmod
Module Size Used by
prism2_usb 60755 1
p80211 24844 1 prism2_usb

This causes the kernel to panic when I do 'reboot' but everything else
seems fine.

How could I go about solving this problem. I had no problem installing
this card and the softwares on a Fedora core 8 release. In this case,
it seems like some wierd kernel config problem causing errors when I
insert modules. Is there a way to get the config file used to create
the stock kernel in 2007.0 gentoo livecd?

Thanks,
Fei
