FreeBSD oden.valhall 4.0-STABLE FreeBSD 4.0-STABLE #30: Mon Jun 12 14:09:58 CEST 2000     root@oden.valhall:/usr/src/sys/compile/JOHANS_KERNEL  i386
>Description:
I upgraded the kernel-source using cvsup and the /usr/share/example/cvsup/4.x-stable-supfile
Then i compiled the new kernel... it took over 20 re-writings of the config-file I wrote until it wanted to boot.
After that I could not use `top`, so recompiled the kvm-libs, and then the top-program almost works (it bugs showing wish program that have what pid).
But, my computer was WAY slower now then it was before the new kernel, so i think that FreeBSD dont use both my cpu's. I got an AbitBP6-moderboard with 2 celeron 366mhz (unclocked) on.
Before i could compile things and use programs at the same time without any problems, now the programs is VERY slow when i do more then one thing at the same time.

The kernel find the 2 cpu's in the boot, but i dont think it uses both the cpu's when the system is running.
Here is an output from dmesg|grep -i cpu:
CPU: Pentium II/Pentium II Xeon/Celeron (367.50-MHz 686-class CPU)
 cpu0 (BSP): apic id:  0, version: 0x00040011, at 0xfee00000
 cpu1 (AP):  apic id:  1, version: 0x00040011, at 0xfee00000
SMP: AP CPU #1 Launched!

How can i fix so the system is as fast as it was with the original-source when i compiled it for smp, and how do i fix top (and ps)? Why do top and ps bug?

I am NOT good at english, and i realy hope you can understand me anyway, if not, please email me and ask becouse i realy want to fix this problems.
I can send you my config-file i use when i compile the kernel if you want it.
>How-To-Repeat:
just cvsup down the latest kernel-source and compile the new kernel.
>Fix:
None... =(
