On a Dell latitude D810 with an ipw2200, yep problems with the new 
2.6.9-42.0.2.EL kernel and the new 2.6.9-42.0.2.plus.c4 centosplus kernel 
and the new 2.4 ipw firmware installed.

An old 2.6.9-34.107.plus centosplus kernel works fine but this uses the 
earlier 2.2 ipw firmware.

I'm using the centosplus kernels to get firewire working but that's 
another matter ;-)

I've installed the new 2.4 firmware. Left the old stuff there, for the old 
kernel, maybe that's the problem. Anyway when I boot with the new kernels 
the network takes a long time, 10's of seconds, to start. Then it 
generally works for a time, 5 to 10 minutes, then stops dead!!!

Using "dmesg | grep ipw" the wireless card is detected Ok but then there 
is an error 

Unknown notification: subtype=40,flags=0xa0,size=40

Any ideas.

I'm going to have a look at this when I get home tonight.

Tony
