no shell prompt

[Manju Mahajan]

 we are using
OS : linux 2.4.31
TARGET: powerpc405
dev platform : i386
boot : u-boot
cross-compiler : buildroot cross-compiler.
( selected 2.4.31 headers, binutils 2.16, gcc 3.4.2 version, no daily snapshot update)

version of busybox is 1.01


I am not able to get the shell prompt

I tried various things 
1. build busybox as static binary, still : no shell prompt
   ( packed this busybox with denx sample ramdisk)
2. Checked permissions on the binary all the executable.
3. disabled the tty1, tty2, tty3, and enabled ttyS0 with 9600 baud rate.: no prompt
Started adding debugs
1. in init.c , it is stuck in while loop, cleaning up the dead processes, (seems like, as soon /bin/sh is spawned it dies)
2, changed inittab to run other /bin/dmsg, it prints the output fine
3. added /bin/login , and i get 
uclibc login: root
uclibc login:

seems like login is also working but no shell prompt after this.

here is the inttab file

( tried the busybox version 1.0 same problem)
Any help is highly appreciated
