I reproed this, and as you can see from the transcripts you
give the problem is that the mux is confused about what the
active console should be. Before the patch, we correctly
start with the serial as the active console and C-a c
switches, but afterwards we start out with the monitor
active and C-a c doesn't switch. Revert pushed to master.
