How to simulate or trigger a Machine Check Exception?

Question

I've setup the mcelog tool on my Linux server, and I'd like to verify that it's working properly but I'm not sure how to test it.

Does anyone know of any ways to generate or trigger an exception event so I confirm that the hardware errors are logged correctly.

Answer 1

mcelog includes a test suite with a tool called mce-inject, designed to do exactly this. The developer has a copy of the source on github. It seems to require Linux 2.6.31 or better.
