Title:
  Thinkpad T460S won't boot with latest intel-microcode update

Status in intel-microcode package in Ubuntu:
  New

Bug description:
  This morning I installed the security update "3.20200609.0ubuntu0.20.04.0" of intel microcode and then, after rebooting, my T460S laptop is stuck with the "loading initial ramdisk" message.
  Selecting an older kernel did not help.

  What I had to do to recover is boot on a live session, chroot into my
  system, rollback to intel-microcode version "3.20191115.1ubuntu3" then
  regenerating initramfs.

  Then I was able to reboot normally.

  Note that my BIOS/firmware is up-to-date (according to "fwupdmgr
  update").
