Help in setting up serial console on 64 bit machine

[Dachepalli, Sudhir]

Hello SerialConsole user,
 
         I have a problem while setting up serial console to direct kernel
printk
messages to serial console. I dont see messages getting displayed.
 
My setup
---------
1. IA 64 machine.
2. Redhat AS 3.0
3. Kernel 2.4.18-e.37smp
4. Server Hardware : HP rx5670
 
Serial Console setup
--------------------
1. I have connected serial cable between two linux terminals.
2. open minicom on both servers.
3. changed the settings to 9600-8-n-1, no h/w flow control, no s/w flow
control, stop bits =1.
4. I typed some charecters on server 1 and saw the charecters appear in
server 2's minicom.
5. I typed some charecters on server 2 and saw the charecters appear in
server 1's minicom.
6. I have changed the kernel command line for booting the kernel . PLEASE
SEE BELOW FOR "elilo.conf".
7. label=serial ( elilo  entry to boot the serial console setup. )
8. I have also checked the options in "make menuconfig" and found everything
correct for serial console setup.
 
After selecting "label=serial" and botting the OS the following is the
command line from proc.
[root@beast root]# cat /proc/cmdline
BOOT_IMAGE=scsi0:EFI\redhat\vmlinuz-2.4.18-e.37smp  root=LABEL=/
console=ttyS1,9600n8 console=tty0 ro
 
The kernel cmdline seems to be correct but the messages are not directed on
console.
I have setup serial consoles on 32 bit machines earlier, but not on 64 bit.
 
Please throw me some pointers to make it work.
 
 
regards,
sudhir dachepalli
