preseed installer fails to detect disks when NIC is specified

[ananke]

When performing an unattended install of Ubuntu 16.04 via PXE & preseed, the installer fails to detect any storage devices when netcfg/choose_interface=eno1 is passed as an option.

If that option is not provided via APPEND, or set to 'auto', installer detects storage devices just fine.

Sample APPEND that will result in a failure to detect any storage devices:

APPEND auto=true vga=788 preseed/interactive=false netcfg/choose_interface=eno1 initrd=/images/linuxdistros/ubuntu/16.04/amd64/initrd.gz preseed/url=http://MYDOMAIN/preseed/ubuntu-16.04-preseed.cfg locale=en_US.UTF-8 keyboard-configuration/layoutcode=us hostname=unassigned --

When the 'netcfg/choose_interface=eno1' option is removed, storage devices are detected, also setting it to 'auto' seems to work.

Can you extract and attach /var/log/* files from the d-i environment, when it fails?
