What?

I see :-) It is very odd having a system that shutdowns by its own in two different computers. Are both boxes sharing/using the same piece of hardware? Anyway, a shutdown denotes a critical situation, that can be true or somehow biased but there's something that instructs your system going down and at a first glance, on the hardware side, I would point to the CPU temperature or a bad power supply. On the software side, a bad/ incorrect measurement of sensor trip points can also make the system to think it's hotter than it is in reality and thus triggering a system shutdown. > What I notice is that for no obvious apparent reason the CPU taxes to > the max and the box starts revving wildly ~ When that happens, run "top" and sort the values by CPU load percentage (pressing "C") to see what's the culprit. > I use different live CDs based on linux debian and I am very careful > in order to avoid the regular bs out there ~ > I would like to periodically test the underlying hardware as low as > possible to the bare metal, because if something is messing with your OS > it will be harder for you to notice anything ~ > Any best practices and tips you would share?
