I suppose mcelog might be extended to point at possible tools to get a
second opinion, in case the admin would like to to be entirely
certain. In their position I can understand them when their vendor
asks them if it's the hardware and what tests they've run to rule out
software.

Think for example a machine check that might point to faulty RAM, it
might direct the admin to run memcheck if mcelog alone isn't
compelling enough.

Yikes, ixnay to the <blinkay>. Next people will ask for flash support
