With the changes I've made to the logging and the raw log files we have without any utf-8 conversion, I'm now 99% certain this isn't any utf conversion issue since the login prompts are not in the raw binary files and those are written with no conversion. It is much more likely the getty isn't running or isn't communicating somehow. I'm trying to work out how to add some further debug/testing when this fails in a way it will help us debug.
