what type of messages you have?
Is it a networking issue?
About the inquired patch, as you can easily see via git log, the code
introduced is disabled by default, so I think the keyscan support can be
excluded from the "black" list.
Indeed, if for whatever reason it was enabled and Ethernet disabled (given that its PIOs
conflict with the second ones) it could be a reason of your failures.
One test you can do, other than to check the dt code, is to boot via a usb network cable and
see if the boards mount the nfs filesystem.
