I can confirm now, that that kernel breaks both a desktop (an ThinkPad T440s i5) and a headless server (i3930) setup. For the server the attached .config works fine but switching from CONFIG_GENERIC_CPU to CONFIG_MCORE2 legt them hang at boot w/op any messages. Similar picture at the desktop.
You most likely have the same problem as me: https://lkml.org/lkml/2017/12/29/279
Indeed, I got a similar message at my ThinkPad too when I tried to bisect it:
