Thanks for your response, Fernando.

 From /var/log/messages ==>
Jul  7 18:09:53 localhost kernel: Loaded prism54 driver, version 1.2
Jul  7 18:09:53 localhost kernel: snd_intel8x0: Unknown parameter
...
Jul  7 21:34:00 localhost kernel: usbcore: deregistering driver 
snd-usb-audio

 From dmesg ==>
e100: eth0: e100_probe: addr 0xe8200000, irq 9, MAC addr 08:00:46:68:86:3C
Loaded prism54 driver, version 1.2
snd_intel8x0: Unknown parameter `'
snd_intel8x0: Unknown parameter `'
snd_intel8x0: Unknown parameter `'

if you look at my /proc/asound/cards (below) you'll see that the sound 
card uses irq 9 also.

I didn't seem to have this problem in RH9, FC3 & CCRMA, the same wifi & 
sound cards.

Well, no, in fact, the wifi card is functioning with both the FC4 & 
CCRMA kernels.
Can I change the irq being accessed by the sound card or the network 
card? I thought these problems disappeared with DOS?
