Subjectbalance interrupts

Hello!

Now that my IO-APIC finally works without lockups (thanks to all!) on
my nforce2 boards, my interrupts are much less crowded. However,
there's still one line in /proc/interrupts which I don't really like,
it's also the only line where more than one piece of hardware shares
the same interrupt:

18: 445160 IO-APIC-level ide2, ide3, eth0

ide2 and ide3 are my onboard Silicon Image SATA controller. I guess
you can't keep them apart on to different interrupts, since it's only
one chip which is most probably connected to one IRQ line only.

But I don't think that eth0 has to be on the same interrupt as my SATA
controller. So, how do I make it go away to another place? I would be
fine sharing it with e.g. eth1, which is alone on IRQ 19.

BTW, the whole /proc/interrupts looks like this:

CPU0
0: 40022145 IO-APIC-edge timer
1: 62950 IO-APIC-edge i8042
2: 0 XT-PIC cascade
8: 681626 IO-APIC-edge rtc
9: 0 IO-APIC-level acpi
12: 55 IO-APIC-edge i8042
14: 968274 IO-APIC-edge ide0
15: 1789182 IO-APIC-edge ide1
16: 404489 IO-APIC-level EMU10K1
18: 445160 IO-APIC-level ide2, ide3, eth0
19: 1596427 IO-APIC-level eth1
20: 0 IO-APIC-level ohci_hcd
21: 0 IO-APIC-level NVidia nForce2
22: 36730 IO-APIC-level ohci_hcd
NMI: 0
LOC: 40021891
ERR: 0
MIS: 310
