SMP Interrupt troubles....

Hi all,

I am seeing the following SMP interrupt errors. I have 2.1.90 up and running
smoothly, but as soon as I patch in to 2.1.91,2,3 or 4, I have see the
following in /proc/interrupt:

Kernels 2.1.91,2,3,4

CPU0 CPU1
0: 11504 11273 IO-APIC timer
1: 362 348 IO-APIC keyboard
2: 0 0 XT PIC cascade
8: 1 0 IO-APIC rtc
9: 17361438 17358440 IO-APIC probe
10: 0 0 IO-APIC probe
11: 0 0 IO-APIC probe
12: 0 0 IO-APIC probe
13: 1 0 XT PIC fpu
14: 0 0 IO-APIC probe
15: 0 0 IO-APIC probe
17: 1525 1617 IO-APIC BusLogic BT-958
NMI: 0
IPI: 0

I normally have the following in /proc/interrupt on 2.1.90:

CPU0 CPU1
0: 162515 161880 IO-APIC timer
1: 2032 2044 IO-APIC keyboard
2: 0 0 XT PIC cascade
4: 214437 210932 IO-APIC serial
7: 0 0 IO-APIC Crystal audio controller
8: 0 1 IO-APIC rtc
12: 64754 51228 IO-APIC PS/2 Mouse
13: 1 0 XT PIC fpu
17: 19216 18908 IO-APIC BusLogic BT-958
NMI: 0
IPI: 0

As you can see, my mouse and sound card have disappeared and replaced with
several 'probe'. I have tried to track this one down myself, but I'm not
familiar with SMP code to know where to start looking.

As a consequence of the messed up interrupts, I can no longer start X windows.
I get the following error from startx as I try to start X windows:

Fatal server error:
Cannot open mouse (Device or resource busy)

I am willing to try anything that you can suggest. I really want to help in
assuring that the new kernels are compatible with my board.

Troy
