Yes, it's always the same result: 6 ProcId lines. BUT, I wasn't sure
about how many times "acpi_pcpu_get_id() failed" appeared on previous
test. So I reverted changes on acpi_cpu.c and modified these lines as
before:

%%%%
      acpi_id = obj->Processor.ProcId;
kprintf("Before calling AcpiOsFree()\n");
      AcpiOsFree(obj);
kprintf("After calling AcpiOsFree()\n");
      if (acpi_pcpu_get_id(device_get_unit(dev), &acpi_id, &cpu_id) != 0) {
kprintf("acpi_pcpu_get_id() failed\n");
          return (ENXIO);
      }
kprintf("acpi_id: %d, cpu_id: %d\n", acpi_id, cpu_id);

%%%%

and started taking pictures to get a better shot. After watching them,
I saw that "acpi_pcpu_get_id() failed" appears only 3 times
(http://www.e-nix.com.ar/~maliaga/00003.jpg and
(http://www.e-nix.com.ar/~maliaga/00004.jpg). So sorry, I thought they
were 4 :-(

For this I cvsupped last changes, applied your patch, and tried from
knob 6 to 11. Unfortunately, it didn't lock on any of the tests, and
the messages where the same than previous tests with knob 0 to 5.
