How does that even happen?

Lemme try to understand this correctly: the first kernel gets an
MCE, kdump starts and boots a *whole* kernel and *then* you get the
broadcasted MCE? I have real hard time believing that.

What happened to the approach of clearing CR4.MCE before loading the
kdump kernel, in native_machine_shutdown() or wherever does the kdump
gets loaded...
