FS#2535 - Aerohive HiveAP-121: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

I am having an issue getting two Aerohive AP121 devices to boot properly. I have followed the instructions in the git commit, as shown below.

This was reported in early 2018, but was closed as it was deemed to not be a bug because that report was having the image boot from memory, rather than flash: https://bugs.openwrt.org/index.php?do=details&task_id=1264

Is this an issue of the Aerohive OS boot variables not being compatible with OpenWRT? Or is it something else within the image? Any guidance would be happily accepted to help debug this issue. Remote serial access can be arranged with some lead time.

The same issue occurs with the trunk snapshot as well and is consistently repeatable when following the installation instructions.
