Unable to boot InstallESD.dmg on rMBP with USB Ethernet connected

I'm testing pushing macOS 10.12.3 using the process outlined in the Casper admin guide : 1) policy to cache installer, 2) policy to install cached packages, reboot, boot to installer.

This has worked as expected on all models in our scope (13" MacBook Air, 15" MacBook Pro with Retina) when working wirelessly, and as expected on MacBook Air with USB or Thunderbolt Ethernet adapters.

HOWEVER, when a rMBP with USB Ethernet adapter completes the policy and reboots, the computer stalls at a black screen. Powering off then selecting boot disk (alt) boots returns the computer to 10.11.6. This behavior is not present when a Thunderbolt Ethernet adapter is used.

Has anyone else encountered this behavior when pushing 10.12.3 in this scenario?
15" rMBP, 10.11.6 (patched)
USB Ethernet adapter

I am attempting to push 10.12.0 now to see if the issue is with the 10.12.3 installer and will report back.

Likely has to do with the limitations of the USB adapter, those are only 100Mbps. Not ideal for imaging.

Thanks @hkabik. These computers are already imaged and with the users. We are able to cache the macOS Sierra installer on computers with the USB Ethernet (100Mbps) adapters, its just when the computer reboots that the trouble begins.

Following up on original post: pushing 10.12 installer works -- I was able to successfully boot the InstallESD on 15" rMBP with USB Ethernet adapter. Looks to be with 10.12.3 installer, hoping it will not persist with 10.12.4.
