Hello,

I have an Abit NF7-S motherboard with the network device built in on the
board. It was detected during the Fedora core 2 installation (forcedeth
driver) as you can check in the log below:

Unfortunately when I recompiled the kernel (2.6.6-1.435.2.3), the system
is unable to bring up interface eth0. It disables IRQ 10, which
according to the HW detection is shared by USB 2.0 EHCI controller and
the network controller. This is the log for this kernel:

It seems clear to me that this time, something is wrong with IRQ10, used
by the network controller, and then this IRQ is disabled... so no
network.

If I play a little bit with the BIOS setup, PnP/PCI configurations, the
resources are controlled by Auto (ESCD) by default. If I change this
setting to Manual and I assign IRQ-10 to Reserved instead of PCI Device,
then the network controller uses IRQ-12 and USB 2.0 controller switches
to IRQ-5. This time it's the IRQ-5 which is disabled on Fedora and I
have no problems related to the network.

I guess I'm missing some option when I recompiled the kernel. Any
suggestion?
