[NTLUG:Discuss] Re: Periodic crashes on Redhat 8.0

I can't recall if the original message specified the type of CPU and the
specific system board make and model.

If this is an Athlon XP or MP, they do run VERY hot, and many system boards
made over the last year or so are designed to detect if the CPU is
overheating to a critical level and immediately power down the system if
that is the case.  This drastic behavior is necessary because these
processors run so hot that if their cooling fan should fail, they will
typically self destruct in a matter of a few seconds.

I suppose it is conceivable that on some system boards there could be
deficiencies in the implementation of this shutdown circuit, and maybe it
could trigger when it doesn't really need to.  Or maybe the shtudown
circuit is designed adequately, but one of the components it relies on
fails or begins to exhibit flaky behavior, such as its temperature sensor.

So what type of CPU and system board is in the system?
