inittable and login problem

[Lei Sun]

Hi:
   My inittab contain following line

tty1::respawn:/sbin/getty 38400 tty1
tty2::respawn:/sbin/getty 38400 tty2

# Put a getty on the serial port
ttyS0::respawn:/sbin/getty -L ttyS0 115200 vt100

when i boot up, it keep poping up
"bumper, cannot open /dev/tty1"
"bumper, cannot open /dev/tty2"

I was using serial console on a MPC8260ADS board, if I comment out
those 2 tty line, I can get login prompt, but after I typed in user
name, the password prompt came out(prepended with a wide space), but
it won't accept any thing I typed in, and after 60 seconds, login
expired.

Any idea?

Thanks
