Problem Serial console with Redhat Enterprise Version 3. Diego_Leccardi at
Fri Mar 11 09:40:30 CST 2005

Hi ya,

I configured "Serial Port Redirection" as per the following article and
it always worked fine:

I think that there are two errors in the configuration:

> serial console splashimage=(hd0,1)/grub/splash.xpm.gz

This should be commented out

>        kernel /vmlinuz-2.4.21-20.0.1.ELsmp ro root=LABEL=/
>        console=tty0 console=ttyS0,19200n8r

These two lines must be on the same line and not two separate lines.

Just so you don't feel abandoned, since no one on the list has
We have the same issue that you are experiencing on the floowing
3x PE6650
2x PE2650
4x PE1750

and last but not least, 1 Optiplex Workstation that i used to test
various options.

Kernel messages display just fine, then the display stops after init
until the login prompt appears.
no boot messages at all, yet if I use 'service' to stop/start/restart
while logged into the console, the messages display just fine.

You are not alone, but no one here seems to have any clue as to what is
going on.
I also tried a few RHEL/Dell IRC channels and got a little farther, but
no solution was ever found.

If you do figure it out, please pass the information along.
