Hi Mojtaba,

I got a similar error on my ML-310 when I tried a new root filesystem.
 As far as I recall, I needed to make sure that two entries existed in
/dev, namely:

crw-------    1 root     root       5,   1 Jan  1 05:18 console
crw-rw----    1 root     root       1,   3 Dec 10  2007 null

I think that you are missing /dev/console and then init cannot run
since it has nowhere to put its standard output.

You can make those by mounting your CF card on your development host
and (as root) make the nodes:

# mknod -m 660 /dev/console c 5 1
# mknod -m 660 /dev/null c 1 3

In my case, I use the UartLite (ttyUL0) serial port driver, but I'm
pretty sure this is going to fix the problem you are observing.
