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.

Hi BJ
I made a similar problem go away on my Compaq nc6320 by installing a
custom ASL, see
http://www.freebsd.org/doc/en/books/handbook/acpi-debug.html and
http://lists.freebsd.org/pipermail/freebsd-acpi/2009-March/005562.html
My issue was with _CRT not _TMP. The whole thread is long but it's got
some useful background.
Basically you create an ASL (see handbook), figure out exactly where
_TMP is set, figure out what alternative values set it to a non-absurd
value. Testing the alternative values is trial and error and involves
installing a modified AML (see handbook) and rebooting.
best of luck and when you get a working modified AML keep it somewhere
for when you reinstall...
