Problems getting linux working on MPC8260ADS

Hi All

I have a problem booting linux 2.4.20 on the MPC8260ADS board. The
kernel comes up without problems, but I can not seem to get sh or init
working properly.  As sh starts, I do not see any output on the console.
If I type something (like ls), it is echoed back to the console, but no
result comes back. I am using a NFS file system. If I do something like

echo "hallo" > file

the file is created on the NFS file system with the right entry.
However, after some time the system seems to stop responding.

If I run init, it get stuck somewhere while executing rc.sysinit (see

Any help will be appreciated.
