Any thoughts on specifics, or any clues as to how to try and address it? (Hardware, power related, cosmic rays, etc?) Does the error being deferred have any important relevance vs being undeferred? Right now my initial plan is to wait and see if it happens again. If so I'll probably try disabling ECO mode in BIOS, unless anyone has anything more helpful or directed to try and move forward with.

I recently got a random MCE event (not related to boot) and am looking for help determining why. I've attached Diagnostics and syslog.
