Really?  The lines after 219 until the next kprintf inserted look
like this, right?

   226      acpi_id = obj->Processor.ProcId;
   227      AcpiOsFree(obj);

Yes, those are the lines.

Hmm.. what happens if you undo the patch, and change above code to:
%%%%
        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);
%%%%
without debug.acpi.layer or debug.acpi.level in /boot/loader.conf.
This is what I get: http://www.e-nix.com.ar/~maliaga/00002.jpg

BTW, to specify "all ACPI-CA components except for namespace and processor",
you can change it to:
        AcpiDbgLayer = ACPI_ALL_COMPONENTS & ~(ACPI_NAMESPACE | ACPI_PROCESSOR);
Thanks for this, I didn't know how to do it.
