Hi
with kernel 2.4.21-pre2:
pc:~ # cat /proc/interrupts CPU0 CPU1 0: 29372 0 IO-APIC-edge timer 1: 504 0 IO-APIC-edge keyboard 2: 0 0 XT-PIC cascade 8: 2 0 IO-APIC-edge rtc 9: 0 0 IO-APIC-edge acpi 12: 8078 0 IO-APIC-edge PS/2 Mouse 14: 7 0 IO-APIC-edge ide0 16: 8690 0 IO-APIC-level aic7xxx 18: 241 0 IO-APIC-level eth0 NMI: 0 0 LOC: 29276 29275 ERR: 0 MIS: 0
Booting with "noapic" or "acpi=off" doesn't make a difference. With kernel 2.4.20 both CPU's handled the same amount of interrupts. I haven't checked this with 2.4.21-pre1.
The CPU's are PIII@500
