Hello Dimitri, or anyone else affected,

Accepted amd64-microcode into bionic-proposed. The package will build
now and be available at
https://launchpad.net/ubuntu/+source/amd64-microcode/3.20181128.1~ubuntu0.18.04.1
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See

to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at

Bug description:
  [Impact]

   * It is hard to generate initrd, with all microcodes included because the initramfs hook ignores
     preset defaults. Adjust hook to take preset defaults into account.

  [Test Case]

   * Install new package, and check that initrd with default settings (i.e. modules=most) has amd64
     microcode included. And that with modules=dep|list it only does so, if one is on AMD cpu.

   * Install initramfs-tools-ubuntu-core from snap image PPA, the resulting initrd should contian
     both amd64 and intel microcode, despite using modules=list, due to the conf.d default settings
     it overrides.

  [Regression Potential]

   * The hook default behaviour is not changed, only integration with
  custom conf.d's is improved.
