Description dh 2000-05-31 19:40:01 UTC 
lots of disk IO causes this crash:

mp_lock 01000001 cpuid 1 lapic.id = 0

ip = 0x8:0xc02ca46f
eflags = iterrupt neabled, iopl=0
current process = idle
int mask = none <- SMP: XXX
kernel: type 29 trap, code=0

I look at the kernel symbol table.
that ip is in 'idle_loop'

Fix: 

use UP mode:(
How-To-Repeat: do lots of disk IO
