True:

Second CPU is disabled.

The FreeBSD say so:

> APIC: Using the MADT enumerator.
> MADT: Found CPU APIC ID 3 ACPI ID 0: enabled
> SMP: Added CPU 3 (AP)
> MADT: Found CPU APIC ID 0 ACPI ID 1: disabled


It may be CPU failure detected during POST. Or broken CMOS content, 
sometime (try clear CMOS content).
