[Bug 1759920] [NEW] linux-image-4.13.0-37-generic locks up at login screen with intel-microcode 3.20180312.0

[Erich E. Hoover]

Public bug reported:

I don't know if this is a problem with the kernel or the microcode, but
we have a significant number of computers in our organization (on both
16.04 and 17.10) that fail if they have both updated.  Booting with
either linux-image-4.13.0-36-generic or intel-microcode
3.20180108.0+really20170707ubuntu17.10.1 allows all these computers to
boot.
