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.
