I'm not sure how to begin debugging this -- in particular, how to decide if it's because the notebook isn't cooling properly (perhaps due to ACPI or hardware?) or if we're failing to turn it back down against once it is cooled (perhaps also due to ACPI?). Regardless, it actually has the effect of generating quite a bit more noise, and using moderately more battery, so any pointers on where to start looking for helpful. Thanks, Robert N M Watson
