I don't have a record of it, but as I remember, when that happened I had APIC enabled in the BIOS. After that, I switched to PIC.
In this machine's BIOS Setup BIOS FEATURES SETUP screen, there's the line:
Interrupt Mode : PIC
The other option is APIC. Make sure it says PIC.
I think it was Alan Cox who pointed out that on single-processor systems you need to have PIC, and not APIC enabled. And my kernel wasn't even built with APIC support ("# CONFIG_X86_UP_APIC is not set").
APIC is a newer interrupt controller type, PIC is the orginal 8259A type. These chipsets can emulate either type in hardware.
I don't know if that's your problem, but you might check.
