I have a Compaq Presario SR2180NX, which uses a P5LP-LE motherboard.

When I bought the machine second hand three years ago, I originally installed and ran FreeBSD 5.5 without the error message.  I recall that it began appearing after I installed and ran 6.3, though I don't think it did under 6.2.  I still receive the message now that I'm running FreeBSD 8.0.

I've looked at some of the ACPI code file and didn't notice anything obvious which might be responsible for the error message.  A quick solution I've used is running a file with:

hw.acpi.thermal.user_override: 0 -> 1
hw.acpi.thermal.polling_rate: 10 -> 1800
hw.acpi.thermal.user_override: 1 -> 0

shortly after logging in as root.  The message still appears but not as often, though it doesn't fix the whatever causes the error.

I've installed FreeBSD on two different models of IBM ThinkPad without the error, leading me to believe that the ACPI code might not be completely compatible with the P5LP-LE motherboard.

My question is what to do next.  Is there a permanent solution to this or do I have to keep using the quick fix?

Any advice would be appreciated.  Thank you.

BMJ
