Thanks, that worked. Now at least the ethernet IRQs are fielded by both
processors. However, the other IRQs are still handled by CPU0 solely:
CPU0 CPU1
0: 25411781 0 IO-APIC-edge timer
1: 2 0 IO-APIC-edge keyboard
2: 0 0 XT-PIC cascade
8: 1 0 IO-APIC-edge rtc
11: 502144 505080 IO-APIC-level eth0
14: 82516 0 IO-APIC-edge ide0
15: 2 0 IO-APIC-edge ide1
NMI: 0 0
LOC: 25412978 25412977
ERR: 0
MIS: 0
This differs for example from the table Vladimir G. Ivanovic
<vladimir@acm.org> showed in his posting "Re: Dual Processor":

Does anybody have a suggestion for getting the IRQs for the harddisks
etc. fielded equally in this case ?
