[Bug 1759920] Re: intel-microcode 3.20180312.0 causes lockup at login screen(w/ linux-image-4.13.0-37-generic)

[Tyler Hicks]

I'm still unable to reproduce these lock ups and I've tested on three
different systems. So, I'm reliant on you (very helpful) bug reporters.

Could someone test out the 4.13.0-38-generic kernel from artful-proposed
to see if you experience any lock ups with the 3.20180312.0 microcode?

In the meantime, I'm looking through the changes between 4.13.0-36 and
4.13.0-37 to see if there's anything that sticks out. Nearly all of the
changes are ARM related so that limits the possibilities in a nice way.

Bug description:
  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.
