If this message stair-steps across your screen and you can't do
a ^D, the file /etc/ioctl.syscon has become corrupt. Go into
single- user mode by typing the root password followed by ^J
instead of a carriage return. Use stty
sane^J to restore your console to more normal operation.
Remove /etc/ioctl.syscon, and reboot by running /etc/reboot.
The system will complain that /etc/ioctl.syscon is missing and will
rebuild it for you.
The usual cause for this file becoming corrupt was that the
system was shut down from a terminal other than the console, and
this file now contains the stty settings for that terminal (which
are probably not correct for the console).
Also: /dev/console, /dev/syscon, /dev/systty should all be device 3,1. Use "ln -f" if one or more is bad.
