They look a lot like what https://review.coreboot.org/28443 fixed. You could check if commit dfaff4d18a711f764c9198f488435fdc553dcea2 exists on 4.8.1 (if it does not, there's your problem).
I manually applied the linked patch to my local coreboot-4.8.1 and no longer see those mce messages. Thank you Angel!

Ill port a heads build with> 4.11 for Sven (and myself, as I have the same issue) and see if that resolves.
That might still be worthwhile, but if you just want to get rid of the mce errors the patch linked by Angel does the trick.
Cheers, /Sven
PS: I'll stay around and learn. Thanks everyone!
