That does filter the output, but not the messages I was looking for.
Looking at /var/log/messages tells me the lines should be something like
this:

 kernel: [381990.959785] CPU3: Core temperature above threshold, cpu clock throttled (total events = 38)

But I still can't find where it says shutting down.  Anyway, what
subsystem is the above?  Also how can I limit it to kernel messages from
all subsystems?

Thanks for your response,
