That shouldn't happen, unless the port becomes disabled (eg, you're
not using the LL-debug port as your console, and its then placed into
a low power mode.)

Again, let me re-interate what LL-debug is for: it's there to assist
getting the early boot up and running. Once the early boot is working,
it should *not* be used.
