Title:
  Dell Latitude 7300, i7-8665U, sig=0x806ec/20200609: hangs on Whiskey
  Lake

Status in intel-microcode package in Ubuntu:
  Confirmed

Bug description:
  Basically the same symptoms as #1882809, but with 20.04 and on an
  i7-8665U (Dell Latitude 7300).

  Affected version is 3.20200609.0ubuntu0.20.04.0 (tested with kernels
  5.4.0-33 and 5.4.0-37)

  CPU:
  Vendor ID:                       GenuineIntel
  CPU family:                      6
  Model:                           142
  Model name:                      Intel(R) Core(TM) i7-8665U CPU @ 1.90GHz
  Stepping:                        12

  microcode: sig=0x806ec, pf=0x80, revision=0xca

  The first sign of a problem was a hard lockup while processing the new
  microcode package as part of a larger update; after fixing the
  resulting mess and completing the update (which regenerated the
  initramfs) I started having random lockups early in the boot process,
  with just "Loading initramfs" printed on the console.

  Downgrading intel-microcode to 3.20191115.1ubuntu3 and regenerating
  the initramfs fixes the problem.
