Laptops do get warm - especially if people do dumb things like restrict airflow to where its needed - but if its getting too warm to use then something's amiss. Powerd and friends job isn't to prevent the CPU from overheating, its to step the CPU down a notch when its not being asked to do intensive tasks. If your laptop can't sustain intensive tasks without crashing then there's a fault in the laptop, either the design or your specific unit. Graph the temperatures and see if the laptop runs noticably warmer under FreeBSD than Linux. You might just find that "more work" is being done under FreeBSD and its causing your hardware to fail. The backtraces are useless if your hardware is at fault. Discount the hardware being at fault first. 2c, adrian (Who gave up trying to make this crap work on PCs and just bought an iBook.= .)
