Are you booting with the new intel u-code? Are you fairly sure this is a Intel microcode issue? I'm not completely certain; but it would make sense. I'd test it out. Thank you for your help thus far. I'll examine this further tomorrow, g'night. From rasmus first post: I'm experiencing machine check exceptions since every kernel after package linux-3.11.5-1 (Oct 14 2013) New intel microcode was only introduced with kernel 3.17 ... It's unlikely to have to do with this issue.
install mcelog, run it as the log tells you and post the result. Thank you for your new, important thoughts. I put the lines in a file called mce.log.

I never did use the mcelog tool before, but to me it looks like not much of an analysis, perhaps I'm doing it wrong.
To Rasmus, Looks like a microcode error, please try to add the intel-ucode to your kernel cmdline.
