ACPI Embedded Controller (EC) errors on 7.0-STABLE

[Alexander Sack]

Hello:

I've just installed FreeBSD-7.0-amd64 on my new MSI-171A (GX710A)
notebook (AMD Turon X2 (dual core)/4GB RAM).  I have flashed to the
latest motherboard BIOS via the MSI website (1.10GA 7/25/2007).  I'm
seeing some ACPI errors on boot which I believe are relatively
harmless but wanted to get confirmation from the list.

Here are the pertinent error messages:

After dumping the ASL, it defines an embedded controller (Device EC)
with a bunch of methods but ACPI-CA complains that there is no
OperationRegion handler for them.  I see 7 error messages which I
believe correspond to the 7 Method AML calls defined.  Is this faulty
ASL code on MSI's part or a regression bug?  Its DSDT specifies ACPI
compliance 1.0 I *think* (I'm a little rusty here).

I've attached all the debugging out I can think of (boot -v dmesg, my
ASL, and sysctl -a hw.acpi).  I do notice that iasl gives me a
compiler error but its seem outside the scope of my dmesg error
output.  I assume based on spec that this is the System Bus, PCI bus
0, south bridge, embedded controller, battery 1 (methods are for
status, information, etc. etc.).

Any feedback would be much appreciated?

Thanks
