;I would suggest sticking with a pre-built rpm if the binaries are
;giving you grief (I've used both without trouble, FWIW).  I don't have
;a clue how to tell you to get back to a clean system, you're on your
;own to undo whatever you've tried so far. :)

;To use the rpm's kindly provided by Axel Thimm, enable the ATrpms repo
;by creating /etc/yum.repos.d/atrpms.repo.  Mine looks like
;this:

;[atrpms]
;name=Fedora Core $releasever - $basearch - ATrpms
;baseurl=http://dl.atrpms.net/fc$releasever-$basearch/atrpms/stable
;enabled=1
;gpgcheck=1
;includepkgs=ieee80211-kmdl* ipw3945* lirc* yum-plugin-kmdl

;I have the includepkgs line because I only want a few of the many many
;packages available from ATrpms.

;Next, install the ATrpms GPG Key:

;rpm --import http://ATrpms.net/RPM-GPG-KEY.atrpms

;Then, install the ipw3945 module for your kernel (yum will take care
;of the dependencies):

;yum install ipw3945-kmdl-$(uname -r)

;AFAIK, the rpms don't take care of starting the required regulatory
;daemon, so you'll want to start that up.  You can put it in
;/etc/rc.local if you like:

;# start the ipw3945 daemon
;/sbin/ipw3945d --quiet

;HTH,

Thanks again for the excellent help. Sadly, I'm still in trouble. I have
followed the above exactly, I hope. However, on booting up and getting
to the login prompt, the screen has a  multi-line error and a Kernel
panic.  That makes it hard to print the whole error here, but it starts
with:
	BUG: spinlock bad magic on CPU#0, net hotplug/2359Tainted:GF    )
and goes on with mentions of "ipw handle"   etc etc
 
	I can overcome this by removing the ipw3945-ucode from /lib/firmware.
but I can't seem to change the error by fiddling with various things.

	By the way, the laptop is a Dell 9400.

Any other ideas would be appreciated.
