Ie are the errors fatal? All attempts to compile the code unless I did that failed. Other occurrences of Local0 result from operations such as Boolean logical tests. At the points where those statements are, something which defines that variable doesn't exist. Something obviously slipped through the compilation.

I first noticed the bug after I went from, as I remember, 6.2 to 6.3. I think the board was made by a major manufacturer. On the other hand, a problem like this is something I'll have to watch for when I finally get around to building my computer. The acpidump/iasl combo is FreeBSD's way of working > round it.
