Bash unreponsive to keyboard

Hi,
   I have created smaller root file system for x86 embedded 
 system. I am successfully able to boot the target with a 
 CF disk with a older kernel vesrion 2.2.17  where as 
 when I build a kernel with version 2.4.18-14 or 2.4.22. 
 kernel goes to bash prompt and then target is unresponsive
 to any key pressed.
   I am able to ping to the target from host. Console 
 displays messages from target( e.g. if I pull ethernet 
 cable, console show eth0: down mesasage etc). What I 
 concluded is, target is alive but not responding to the
 keyboards for 2.4.18-14 or 2.4.22 kernel./proc/tty/driver/serial
 on host shows proper TX on key pressed, and RX when target 
 send data.
  I think I am missing something which 2.4.* kernel needs 
 to configure additional to work with console different 
 than 2.2. 
   Please help.
Thanks,
Narendra Hadke
