only see cpu0 working after rebuilding kernel with SMP support

[Lei Sun]

Hi,

I wanted to enable the second logical CPU on my P4 HT. and...

Something seems to be strange to me as:

All of the processes are running with CPU0 and none is working with CPU1

Here is the steps and places I read and followed

1. I followed the custom kernel documents from
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-building.html
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-config.html
http://www.freebsddiary.org/smp.php

and compiled the custom kernel

and my kernel config:
-------------------------------------------------
...
options         SMP
device          apic                    # I/O APIC
...
-------------------------------------------------

2. Then I compiled the custom kernel, and installed it

3. I check the startup output, and found
SMP: AP CPU #1 Launched!

So my question is, how come in top, only cpu0 is working, and no entry for cpu1?

Thanks in advance:)
