looking at the administrative mail, i saw that I got this in the first
dmesg after install (and so before kernel recompiling)
MPTable: <HP LT 6000 >
FreeBSD/SMP: Multiprocessor System Detected: 4 CPUs
cpu0 (BSP): APIC ID: 0
cpu1 (AP): APIC ID: 1
cpu2 (AP): APIC ID: 2
cpu3 (AP): APIC ID: 4
then
cpu1 on motherboard
cpu2 on motherboard
cpu3 on motherboard
and at the end :
SMP: AP CPU #1 Launched!
SMP: AP CPU #2 Launched!
SMP: AP CPU #3 Launched!
guess that something is missing in the kernel :(
