>Description:
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'
>How-To-Repeat:
do lots of disk IO
>Fix:
use UP mode:(
