After successful installation of Debian Squeeze, I configure the server.
Then, I found an issue for networking.
The setup process is basically similar to Sheeva0 server setup.
But for this machine, I use existing pre-installed SD card for installation of Debian Squeeze. When I create rootfs, I copy the contents of SD card as is.
I found a failure of network interface. It is because of bogus entry in /etc/udev/rules.d/70-persistent-net.rules. I removed it and reboot.
