shutdown does not power down

[Unga]

I tried to enable debugging on ACPI  and see what happens. I did following:


1.     make WITH_KDB=YES WITH_DDB=YES WITH_GDB=YES \
        buildkernel KERNCONF=MYKERNEL

2.    make WITH_KDB=YES WITH_DDB=YES WITH_GDB=YES \
       installkernel KERNCONF=MYKERNEL

3.    cd /sys/modules/acpi/acpi
       make clean
       make ACPI_DEBUG=1
       make install

But I still get following messages when loading acpi.ko:
Preloaded elf kernel "/boot/kernel/kernel" at 0xc0d2a000.
Preloaded elf module "/boot/kernel/acpi.ko" at 0xc0d2a188.
link_elf: symbol db_readline undefined
KLD file acpi.ko - could not finalize loading

How could I enable ACPI debugging on FreeBSD 7.0?

Best regards
