This is a similar thread on Arch Linux:

Includes the comment:
   "Wasn't the 20180108 microcode update retracted because of issues? Maybe we should downgrade back to 20171117."

There is no 20180108 download available at Intel now:

Looks like the latest one is messed up too - at least for some processors.
