>Description:
	I've just got a second hand Microstar MS-6323 motherboard with a
	Pentium 3 733Mhz processor.  This motherboard fails to power down
	whenever I do a 'poweroff' with NetBSD/i386 3.0_STABLE, sources
	from yesterday.

	More in detail, when doing a 'poweroff', the last message I see
	is 'unmounting file systems... done', and later on it gets stalled
	there.

	Per cube@'s suggestion, I've enabled ACPI_DEBUG and set AcpiDbgLevel
	to 0x00200000.  This shows a large trace during shutdown and the
	last function called is ExSystemIoSpaceHandler (inside which the
	system hangs).  At that point, I cannot even enter ddb.

	The kernel is built with ACPI but without APM.  APM is disabled in
	the BIOS.  A 'dmesg' output is attached below.

>How-To-Repeat:
	Get a MS-6323 motherboard, configure a kernel to use ACPI and do a
	'poweroff' or 'shutdown -p now'.
>Fix:
	Unknown.
