Yes you are right.
The system is loaded with LAPIC.
...
Event timer "LAPIC" quality 600
ACPI APIC Table: <INTEL  DENLOW>
FreeBSD/SMP: Multiprocessor System Detected: 8 CPUs
FreeBSD/SMP: 1 package(s) x 4 core(s) x 2 SMT threads
 cpu0 (BSP): APIC ID:  0
 cpu1 (AP): APIC ID:  1
 cpu2 (AP): APIC ID:  2
 cpu3 (AP): APIC ID:  3
 cpu4 (AP): APIC ID:  4
 cpu5 (AP): APIC ID:  5
 cpu6 (AP): APIC ID:  6
 cpu7 (AP): APIC ID:  7
...

But then, through the sysctl overridden in HPET.

Perhaps, ACPI motherboard has short-term memory :)

I'm not sure I can reproduce freeze.
