Darin,

/sbin/init may need to be patched and rebuilt.  CREAD
flag is required for linux kernels > 2.4.3.

Regards,
Brian

This works
ok when I used an older hardhat 1.2 release, but is
failing
when I try to use something newer.  I can telnet in
to the
system, and can send output to /dev/console or
/dev/ttyS0,
and I can even open up a shell on /dev/ttyS1.  Thus
the uart
code appears to be correct.  Terminal flow control
is turned
off.  Other hints from the mail archives didn't
provide any
leads.

The relevant line from inittab is
   /bin/sh < /dev/console > /dev/console 2>
/dev/console

This problem occurs with kernel 2.4.21-pre6 (via
linuxppc-2.4-devel) and 2.4.20-2002-12-04 (from
ftp.denx.de).
