Thanks for reply. I have tried all the flow control combinations 
(XON/OFF, RTS/CTS) but it still remain the same. Since the terminal 
output looks "correct" when the system start, is it possible that the 
problem is caused by the LOCOMO serial initialization? I havn't digged 
in the code yet but want to know any way to prove it. Did anybody link 
up the serial console successfully with collie 2.6 kernel?

Would you share your pooble case with us too, Purdie?

Thanks.
