Hi,ron
The IRQ of sis900 NIC embedded in the mainboad isn't zero,and it can work normally.But the IRQ of rtl8139 NIC in pci sockets (including socket #1, socket #2,socket #3 ) is zero.It seems that these devices are not configed by the kernel,either I set "direct" or "any" mode to probe pci devices.

I am confused by it.
