ppc 4xx ocp emac driver

Hi,
I am trying to bring up the AMCC powerPC 440EP (yosemite) eval board using the wind river linux 2.0.The kernel version is 2.6.21.
I compiled kernel for ppc and cross compiled busybox. I tried to load the kernel and file system using tftp and I got the following message.The kernel exits with kernel panic with signal 11.Am using busybox-1.4.1.
