ACPI Exception on shutdown

[Denis Menshikov]

 Good day,

faced with this problem: when I shutdown the virtual machine (FreeBSD amd64 release-guest) power-off does not occur, a message is displayed:

ACPI Exception: AE_NOT_FOUND, While evaluating Sleep State [\_S5_] (20130823/hwxface-637)
acpi0: AcpiEnterSleepStatePrep failed - AE_NOT_FOUND

The virtual machine is running with the following command:
sudo bhyve -c 2 -s 0,amd_hostbridge -s 1,lpc -s 1:1,ahci-hd,test_hdd -l com1,stdio -a -A -H -P -m 256 -I testvm

What am I doing wrong?
