Actually, I'd like to know first whether the unpatched upstream kernel -
not -rt - is crashing.
And then 4.6-rt.
Because from looking at your splat, you're getting a thresholding
interrupt the moment you enable the local APIC and from staring at the
MCE code upstream, I think we should be prepared for that scenario.
AFAICT, both -rt and upstream should handle that case just fine and I'm
guessing upstream was fixed at some point and -rt grew another fix which
is probably not needed and it should take the upstream one instead...
