Mine does this too. 2.4.20. Iwill dp400 board running dual 2.4Ghz
Xeons with HT enabled.

I have to boot by passing "noapic" to the kernel, otherwise
/cat/proc/interrupts will show the interrupt numbers wrong,
however. not doing this changes nothing.

Can someone help with this? If you can help I can dedicate the
necessary time in getting you whatever info you need.

Thanks
