[ale] Hanging problem.

[Prabhu Kubendran]

Hello Eric,
     Thanxs for u'r ideas. I fixed the problem yesterday. Actually we are trying
to convert linux to a minimal linux and going to embedded it in a target. so i was
in the phase of redusing the linux size. I have reduced the number of tty's to 5
but in the inittab, i missed  to comment the spawning of 6th tty. so after some
time, linux try to spawn the 6th tty and the keyboard hangs.

If u have any ideas about the convertion of linux to embedded linux kindly send
me.

Thanx,
/prabu.
