Well, I guess that kbdrate is yet another dumb x86'ism that will
directly tap the hardware of a PC's keyboard controller...
Well, I may be wrong, but machine check usually means that you are
trying to access non-existing hardware.
There should be other informations displayed about the crash. Those
should allow you to lookup the location of it in System.map
