Title:
  Microcode for 206C2 Westmere EP is missing

Status in intel-microcode package in Ubuntu:
  Confirmed

Bug description:
  After installing / updating new intel-microcode-package
  (3.20180807a.0ubuntu0.16.04.1 or 3.20180807a.0ubuntu0.18.04.1) we got
  no microcode for Intel Westmere EP (CPUID 206C2).

  After replacing /lib/firmware/intel-ucode/ with files from
  https://downloadcenter.intel.com/download/28087/Linux-Processor-
  Microcode-Data-File and update-initramfs -u the new microcode is
  loaded.

  Did you ignore some CPUIDs?
