>Description:
I'm using a Tyan Tiger MP motherboard with
dual AthlonMP's (1.2ghz) with FreeBSD 4.4-RELEASE.

If i compile the kernel without SMP support then
everything works fine. If i compile it with SMP
support then the kernel won't boot.

It starts to boot but freezes before it has
finished loading all modules or completed
most bootup tasks.

There isn't much else to say about the problem.
>How-To-Repeat:
Just recompile the kernel with SMP support and
reboot.
