everything is fine for a standard intel nic.
any idea?
and i cannot bring the interface up. (i've not tried yet with pci=biosirq...)
tried with pci=biosirq kernel commandline -- same result... maybe it is the same result because my kernel supports DIRECT pci access only? i am going to try a pci ANY access kernel now...

unfort it is the same if the kernel (linux-2.6.0-test10-bk1) has bios pci enabled and i use pci=biosirq ...

i have not done epia-m. this problem is due to bad irq_tables.c
run getpir under the standard bios and see what you get.

jan: thanks a lot for the tip with the bridge!!!
it seems that i have to play a little bit more with the interrupts. the e100.o code in linux tells me ``Disabling IRQ #10'' and/or ``Disabling IRQ #12'' (depending on the values in dualenetaIrq[4] and dualenetbIrq[4]) when bringing up the nics. and then one or both of the nics dont work...

you see the pci-to-pci bridge ?
in general multi-port network-card have a pci-to-pci bridge and an interal pci-bus for the different interfaces.

I think somebody just plugged in a bad irq_tables.c
So test that one you have, if it works, tell me and I'll put it into the tree.
