I made no provision for forced shutdown in case of overheat, which is quite likely to happen if, for example the main ventilation fan went down for some reason. Well, that happened due to stupidity on my part with getting used to the new setup. I fired up a computer and neglected to turn the fan on. Then left it running overnight. Well, given the confined space and very little/no ventilation (of my homemade structure) the computer got hot... Sometime this morning I see syslog messages written to tty that say: Message from syslogd@reader at Sat Sep 30 04:41:32 2006 ... reader kernel: CPU0: Temperature above threshold Message from syslogd@reader at Sat Sep 30 04:41:32 2006 ... reader kernel: CPU0: Running in modulated clock mode [...] Some kind of attempt by kernel to cool things down. But will it actually shutdown if it gets dangerously hot? Further, how can I discover what temperatures were involved when this happened? Or can I set something to make a shutdown happen at a specific temperature? A nicer solution would be somekind of added stand alone temperature monitor in the enclosure that causes a controlled shutdown like one gets with `shutdown -h now'. Anyone here with some experience in this kind of thing that can steer me to some good information? -- gentoo-user@gentoo.org mailing list
