I have seen these errors before on an MVME2301.   My problem was caused
by not having the proper devices in /dev.  I had to add /dev/console and
/dev/ttyS0.  Output from my (working) machine:

 sh-2.03# ls -l /dev/console /dev/ttyS0
crw--w--w-   1 root     root       5,   1 Jul  8 07:19 /dev/console
crw--w--w-   1 root     root       4,  64 Apr 13 08:39 /dev/ttyS0

I also have to give the command boot option:

console=/dev/ttyS0

Now it works.   Good Luck.
