Log Message:
For a polled console incoming characters are buffered on output.
The buffer is never passed to the regular tty routines and can
survive from early boot to halt where it is read by the "press
any continue to reboot" loops.
As a workaround, just kill the read-ahead buffer when switching
from and to polled mode.
