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. 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. BTW, I read through the entire thread. I added the sysctl statements I mentioned in my original message and now the error message appears only every half hour. It's not a proper fix but it reduces the aggravation of having it displayed as often as it was before. Thanks. BMJ <snip> P.S. The version of ACPI is the same one that came originally with the image file that I downloaded off the FreeBSD site.
