I am using two Intel Giga NICs in a DELL PowerEdge 4600
with 2 Intel XEON 1.8GHz CPUs.
The matherboard is ServerWorks GC-HE.
The OS is RedHat 7.2, and the release of kernel is "2.4.7-10smp".
The CPU0 has very heavy interrupt traffic,
you can see the following information:
>>>>>
[root@giga root]# cat /proc/interrupts
CPU0 CPU1
0: 395117 0 IO-APIC-edge timer
1: 653 0 IO-APIC-edge keyboard
2: 0 0 XT-PIC cascade
8: 1 0 IO-APIC-edge rtc
12: 23 0 IO-APIC-edge PS/2 Mouse
14: 2 0 IO-APIC-edge ide0
18: 30 0 IO-APIC-level aic7xxx
19: 86013 0 IO-APIC-level eth0
20: 10394 0 IO-APIC-level aic7xxx
21: 30 0 IO-APIC-level aic7xxx
27: 5480873 0 IO-APIC-level e1000

The kernel's SMP option is enable, but the CPU1 is always idle.
How to balance the interrpupts between two CPUs?
If you are convenient, please give me some advice quickly.
Thank you!
Best regard
