Shutdown Problem

Hi,guys
I have a two CPUs server, and the system is linux2.4.6.
When the system shutdown,it will stop at the word Power Down.
I f I do not select the option "Symmtric multi-processing Support"
when I compile the kernel,system will shutdown automatic.But I
want to use two CPUs.
Anyone can tell me what can I do now ?

thanks

SMP and APM (advanced power management) are known not to work well together. You may be able to get it to work by playing with the APM settings in your BIOS. If not, doesnt seem like too much hassle to just reach down and hit the power button...
