Bah. Also, the reason I started looking into this is that I believe, cpu
cooling is busted. When I compile anything with more -j values, box
shuts down. I don't see any error on console or /var/log/messages but I
did see the temperature going up to dev.cpu.0.temperature: 86.0C right
before it shutdown.

I'll probably reapply the thermal paste and see.
