This is a microcode bug which causes a kernel to hang. So simply booting from a different medium is not going to help you.

You'll need to compile a kernel which does not depend on the RDRAND instruction as a source of randomness.

It causes systemd to blow up, but you could try doing your microcode update from initrd. Or just get rid of systemd, run your microcode update, and make some Halloween jello shots to take to the no-systemd party (it's going to be even crazier, this year).
