I have this motherboard:

	http://www.msicomputer.com/product/p_spec.asp?model=K9NBPM2-FID&class=mb

which claims to be:

	...
	ACPI & PC2001 compliant enhanced power management
	...

I've installed FreeBSD 6.2-RELEASE, updated to patchset 9, and
built/installed the AMD64/SMP kernel,

	uname -a
		FreeBSD server.localhost 6.2-RELEASE-p9 FreeBSD 6.2-RELEASE-p9 #0:
Thu Dec 13 23:15:00 PST 2007
brendonj@server.localhost:/usr/obj/usr/src/sys/SMP  amd64

The system boots fine, with both CPUs active & handling tasks.

However, I notice in dmesg output, few ACPI-related errors.

In #freebsd IRC, it was suggested that I file a PR about this.  But, I
thought I should first figure out if the problem is on my end, or
really with FreeBSD.

Any ideas as to what the problem may be, and suggestions as to what to
do about it?

Thanks

BrendonJ
