full shutdown in smp

I have installed redhat linux 9.0 on P4 HT machine. The grub boot loader shows path to smp mode and normal mode. when machine shut downs from smp version kernal , need to press the power button to power off. But in normal mode the system shut downs or power downs automatically(ie, full shutdown). I installed apm module rpm to solve the issue, but it failed. Can anyone suggest a solution for full shutdown from smp kernel?

Unless the options for smp-mode and single-processor mode are significantly different(what are they?), this sounds like a kernel issue. Have you tried upgrading it? Has anything interesting shown up on dmesg?

hello,

use the smp version of the kernel.

cheers.
