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?
