One thing I did notice, however, is when I compiled
that file and got
two errors arising from:

Store (Local0, Local0)

where Local0 hadn't been defined in that part of the
code.  I have no
idea how that came about, but it successfully compiled
after I
commented out that statement.  (A bug in the
original code, perhaps?) What happens if you recompile an
unmodified ASL?

I got those 2 errors plus a warning.

By errors do you mean that you can't recompile unless you comment out the statement? Ie are the errors fatal?


I bought the machine second-hand from a dealer that was going out of
business.  It came with Vista installed so, presumably, the
motherboard might have been set accordingly.  Updating the BIOS might
help, but I removed Vista when I started tinkering with FreeBSD,
which might make that operation a touch difficult.

Updating the BIOS might help, didn't for me though. If you want to try it, google for a MS-DOS boot disk image to download, either for floppy disk or CDROM depending on what hardware you have.


The main reason I'm concerned about this bug is that I'm planning on
building my own machine and possibly running FreeBSD on it for my
research.  I'd hate to put something together, install FreeBSD, and
have nothing but bugs like this to contend with.

This is a bug introduced by the crappy manufacturer not FreeBSD. The acpidump/iasl combo is FreeBSD's way of working round it. You might want to try on the acpi mailing list if you want to investigate further. I think the acpi section in the handbook says they like to know about such problems.

I don't think it is a common problem. If you are buying a new motherboard you should be able to find something without this problem. Check the hardware notes http://www.freebsd.org/releases/8.0R/hardware.html
