Subjectcommit bd9240a18edfbfa72e957fc2ba831cf1f13ea073 seems to break with intel-ucode 20180425
Hi Peter,

after updating ucode to 20180425 on my laptop I always hit the
'TSC_DEADLINE disabled' error and so early microcode update from
inird breaks.

Also I'm able to late load the microcode from command line but
not from initrd.

Going back to ucode 20180312 make things work again.

I've tested on latest 4.16.8 kernel for now.
