8xx SMC1 problem

Hello everyone,
I have a question regarding the serial init of ttyS0 on a tqm8xx based =
board (823) in denx kernel 2.4.25.

First of, I have three serial ports (SMC1, SMC2 and SCC3) and they all =
work fine when the console is on SMC1. I have gadgets connected to SMC2 =
and SCC3 and now I need SMC1 for yet another device. So I have undefined =
CONFIG_SERIAL_CONSOLE in the kernel config and I jump out of u-boot =
(which have the console on SMC1) with the argument "console=3Dnone".
When logging in (via telnet) ttyS0 works no more (but S1 and S2 does). =
At random bootups, it is possible to open the port but it is no good for =
read or write.

Can anybody give me some advise on how to enable SMC1 but at the same =
time don't have a console on it?

Regards,
