I recall that it began appearing after I installed and ran 6.3, though I don't think it did under 6.2.

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...
