Keywords: console hangs in mid reboot


This question has already been answered several times in this group, to
my knowledge.  Apparently it bears repeating again.  The problem is that
the console tty is running slower than the output data is being sent to
it.  When its internal buffer fills up, it sends a ^S, later it sends a
^Q.  Since the tty driver hasn't been "started" yet, the ^S is still in
the (hardware) input buffer and the ^Q is dropped.  When the console
driver becomes active it reads the ^S and dutifully stops output until a
character is typed.

A solution is to lower the baud rate of your console interface or to get
a console that can print faster.
