I don't see anything in your dmesg about the APIC devices that should be
there.  Did you somehow omit that from your kernel config, or have it
disabled in /boot/loader.conf?  Without the apic device, the other CPU's
can't get started.  Can you run 'acpidump -d -t' and 'mptable'?  Are you
running an i386 or amd64 kernel?
