[Bug 1631474] Re: No networking with initramfs-tools 0.122ubuntu8.3 and ip=dhcp boot option

Here's the initial portion of console output, with only a couple of
minor redactions related to keys, hostname, MAC address.

The most important bit is:

ip: SIOCGIFFLAGS: No such device
Error getting hardware address for "dhcp": No such device

Where the "ip=dhcp" kernel is not being processed correctly per kernel
documentation - see
https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt

Title:
  No networking with initramfs-tools 0.122ubuntu8.3 and ip=dhcp boot
  option

Status in initramfs-tools package in Ubuntu:
  New

Bug description:
  initramfs-tools 0.122ubuntu8.3 introduced a serious regression where
  networking is not initialized when the boot option "ip=dhcp" is
  provided. We are seeing this problem in AWS, but cannot confirm if
  this issue is specific to AWS or will occur with different hardware or
  in different environments.

  Removing "ip=dhcp" from the boot options with 0.122ubuntu8.3 results
  in networking being configured.

  The issue does not occur with 0.122ubuntu8.2 or previous versions when
  "ip=dhcp" is set.

  AWS has no console so debugging is not a trivial task. I do have a
  console log with some output, and will update this bug shortly with
  it.
