I have a dell vostro 1520 I'm trying to set up. lspci says

Code:
0e:00.0 Network controller [0280]: Broadcom Corporation BCM4322
802.11a/b/g/n Wireless LAN Controller [14e4:432b] (rev 01)


which I understand means I need to use the broadcom-sta module. I emerged that
with no problems (modulo annoyance at the licence) but now
Code:
modprobe wl

gives me
Code:
FATAL: Error inserting wl
(/lib/modules/2.6.31-gentoo-r6/net/wireless/wl.ko): Invalid module format

dmesg says:
[ 6495.983904] wl: version magic '2.6.31-gentoo-r6 SMP preempt mod_unload
CORE2 ' should be '2.6.31-gentoo-r6 SMP mod_unload 686 '

What''s the simplest solution?

Thanks
Graham

You have to modify your kernel configuration and build it again.

Try to change the Proc. type and feat. -> Preemption Model to "Desktop" for the first part of th problem.
And dmesg says you should use the i686 achitecture instead of core 2. Did you specify your cpu correctly?

/proc/cpuinfo says:

Code:
model name      : Intel(R) Core(TM)2 Duo CPU     T6670  @ 2.20GHz


so I thought the problem was with broadcom-sta, not with my kernel?

the ebuild unfortunately does not stop you from emerging broadcom-sta even if you have incorrect kernel configuration settings. (I tried to change this, got shot down :) )

Have a look at the settings I/we outlined here:

If lost or in doubt, head to pastebin and dump your kernel .config on up there. broadcom-sta is very very finicky about what options you have selected.
