The problem is CPU1 receives 38239 interrupt-16
but CPU0 receives only 15 interrupt-16
CPU0 should receive more interrupts.

CPU0 CPU1
0: 85 0 IO-APIC-edge timer
1: 0 698 IO-APIC-edge i8042
6: 0 5 IO-APIC-edge floppy
8: 0 1 IO-APIC-edge rtc
9: 0 0 IO-APIC-fasteoi acpi
12: 0 114 IO-APIC-edge i8042
14: 369 2281 IO-APIC-edge ide0
15: 0 24 IO-APIC-edge ide1
16: 15 38239 IO-APIC-fasteoi yenta, pcnet_cs <<< problem
17: 0 0 IO-APIC-fasteoi yenta
NMI: 0 0
LOC: 50548 50547
ERR: 0
MIS: 15503


Best Regards
