So I guess it’s a good idea to try a “vanilla” Ubuntu live USB.

  Regression in 2017-07-07 updates

Status in intel-microcode package in Ubuntu:
  Incomplete

Bug description:
  The version "3.20180108.0+really20170707ubuntu17.10.1" of the package "intel-microcode" randomly freezes Ubuntu at boot (at a very early stage, nothing is written on the screen).
  The number of hard reset of the computer required looks random but it works at third boot most of the time.

  I was previously affected by the 20180808 regression :
  https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1742933
  Symptoms are the same.

  user at PC:~$ dmesg | grep microcode
  [    0.000000] microcode: microcode updated early to revision 0xba, date = 2017-04-09
  [    0.986254] microcode: sig=0x506e3, pf=0x20, revision=0xba
  [    0.986730] microcode: Microcode Update Driver: v2.2.
  If I uninstall "intel-microcode" everything is fine.

  user at PC:~$ lsb_release -rd
  Description:	Ubuntu 17.10
  Release:	17.10
  This install is relatively fresh as I did it when I was affected by the 20180808 regression.
  Xubuntu 17.10 installed on a SSD with LUKS encryption

  user at PC:~$ uname -a
  Linux PC 4.13.0-32-generic #35-Ubuntu SMP Thu Jan 25 09:13:46 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

  Package Manager = synaptic 0.84.2

  Computer :
  Model = Asus N752VX-GC164T
  Bios = v301 (13 oct 2016)
  Processor = Intel Core i7-6700HQ (6th gen Skylake)
  Nvidia graphic card = Grub is configured with "nouveau.modeset=0"

  Sorry I can't give more accurate description of the bug.
  I don't see any error message on the screen at boot.
  Is there somewhere a boot log I can provide ?
