Fair enough.
!CREAD is the most obvious cause, so that should definitely be ruled
out first. If CREAD is clear, we need to figure out why...
So I tested this by booting to my console, and then typing in:
stty -cread
and when I did that, the console ignored all input.
I do admit that since !CREAD has been ignored for so many reason, it
could be that a lot of userspaces will suddenly have broken consoles.
