It is confirmed that wireless and sound have an IRQ conflict. If i

well (see below)), but can't have wireless. Moreover, in the first
scenario, trying to use sound (even xmms) causes wireless to stop
working until i log out, and re-login The message is:
Listening on Device /dev/pts/3
localhost kernel: Disabling IRQ #5.
The IDE, audio, modem , VGA compatible controller, FireWire, CardBus
bridge, and USB Controller use IRQ 10. Wireless, and again USB
controller use IRQ 5, according to lspci -v.
My kernel is 2.6.5-1.358.
Sounds like one absence of a suitable sound card driver is causing all
the grief. There was no sound until i installed the latest alsa-driver,
and now there is a conflict, because sound ends up using IRQ 5. It
actually makes some sense: both modem (wireless), and sound end up in
IRQ 5. So it appears there needs to be a driver that handles both audio
and modem sides of the card, for it not to have an IRQ conflict. And as
far as i see, neither atiixp, nor atiixp-modem drivers meet this
requirement yet.
This would be my first experience with improving a driver, but any tips
on where to start improving one of the drivers above would be appreciated.

Although not optimal, you may have to disable the onboard sound and
install an inexpensive sound card. I have found this necessary at times
when I could not get the onboard chipset to work correctly.
Also, you might play with the order drivers are loaded. Sometimes that
can make all the difference in the world on the output.
I also would strongly recommend you update to the 2.6.6-1.435.2.3 kernel
and other packages as well before you do anything else. If you have not
updated packages since the install of FC2 there are a lot of packages
that have been updated, including the kernel (twice) and most of the
alsa packages.
Thanks for your reply. I upgraded the kernel and updated all other
packages installed. I also uninstalled the wireless driver.
atiixp still suffers from a IRQ conflict, w/ "codec read timeout".
While atiixp-modem complains about /dev/pts/0: no such file or
directory.
This is not surpising because i already had the latest alsa installed
before upgrade.
It appears that the fix lies in making atiixp-modem driver stable; it
is currently experimental.
