External (YCST, MethodObj) which I believe is truncated; reading section 17.5.42 of the ACPI 3.0a spec (not the latest rev, but it hasn't changed), we see that "MethodObj" is an object type; when MethodObj is present, the spec seems to imply that at least one ReturnType must follow. There's no ReturnType specified, so I'm guessing that ACPI CA doesn't expect a return from YCST and ignores the returned value. I've CC'ed Bob Moore at Intel for his opinion. Bob - I've included darn near no information here, but I think it may be sufficient :-) Does the above description sound familiar? Cheers, Dana
