I had an issue with the console initialisation on serial ports, which I

report is as a result of those changes, or lack of those changes.

Those -mm versions with git-arm in probably have that change.  Ergo
the importance to answer this question about kernel versions.

The problem description sounds like it could have been introduced by
that patch:
