Subject[2.4.21-pre3] APIC routing broken on ASUS P2B-DS
Something broke between 2.4.20 and 2.4.21-pre3 which is causing
interrupts to not be routed the second CPU. I saw the problem on one box
and copied the kernel to another which then had the same problem (both
ASUS P2B-DS boards, one with PIII CPUs, one with PII CPUs).

[sroot@devel:/]# cat /proc/interrupts
CPU0 CPU1
0: 114480 0 IO-APIC-edge timer
1: 2 0 IO-APIC-edge keyboard
2: 0 0 XT-PIC cascade
8: 3 0 IO-APIC-edge rtc
16: 30707 0 IO-APIC-level eth0
19: 3260 0 IO-APIC-level aic7xxx
NMI: 0 0
LOC: 114405 114404
ERR: 0
MIS: 0

With 2.4.20:

[sroot@devel:/root]# cat /proc/interrupts
CPU0 CPU1
0: 23627 27340 IO-APIC-edge timer
1: 0 2 IO-APIC-edge keyboard
2: 0 0 XT-PIC cascade
8: 2 1 IO-APIC-edge rtc
16: 1671 2 IO-APIC-level eth0
19: 965 979 IO-APIC-level aic7xxx
NMI: 0 0
LOC: 50893 50891
ERR: 0
MIS: 0

...If nobody knows what happened immediately, I'll try narrowing it down
to the patch.
