FC4: IRQ 11 rarely enabled -> no wifi, no ethernet

["Daniel Frèrejacque"]

On a recent Toshiba M40, dual boot: windows + FC4,
Pentium M; networking:
(a) Syskonnect SK-98xx Gigabit ethernet (compatible with Marvell Yukon)
(b) Intel Pro Wireless 2200 BG (driver ipw2200 provided)

During the boot process, after udev and
before the clock setting, the message
"Disabling IRQ 11" is displayed.

This happens randomly, but IRQ 11 is more oftent
disabled than enabled. In that case neither wifi
nor etherenet are be activated, nor can be with
the network tools.
         ------------------
(1) Examining dmesg, making diff on dmesg with and
without IRQ 11 ok, there is a message:
"IRQ 11 nobody care" and roughly twenty lines later
the "Disabling IRQ 11"

(2) The advice given in dmesg: in case of harware not
recognized: try "pci=routeirq" (and post a message if ok)
don't change anything.

Note: The driver sk98lin for Gigabit ethernet is not yet
provided by Fedora, but compiled and installed with
modprobe for each new version of the kernel.

If interested, I can forward dmesg with good and bad boots.

Should I post a bug

Thanks
