until we have proper heat control in the kernel, maybe pmud should monitor the temperature and

the machine to sleep if it runs too hot.
i'm looking into this part.
btw, what is a dangerous temperature? with the bays empty and a housefan running nearby (ie relatively cool) it is reporting 42c.
Actually, IBM and Motorola specs say the G3 has an operating temperature of up to 105C!

(Quite different from Intel's stuff, isn't it? ;^)
Before I read that, I used to worry myself when the heat-conducting plate above the cpu was hot to the touch when opening the keyboard (which probably means about 60C). As it is, you'll probably have to worry more about the harddisk and other components.
Still, looking forward for a temperature monitor in pmud :-)
Thanks for your efforts,
Derek

G4s come in a variety of temperature specs, and many of them are only rated up to 65C. You'll have to read the markings on the package to work it out.

There are multiple temperature grades. Desktops usually use parts rated for 65 C, maybe 85 if you're lucky. Apple's early Wall Street G3 laptops used 105 C parts (and needed it), later ones with better cooling may have 85 C.
