ADS860 - unable to load kernel- Bad magic number

I am a linux-newbie working on a parallel track on the MPC 860, on a ADS
board. I am facing difficulty in getting the kernel to load. This is what I
have done so far:

- built a cross-toolchain using Dan Kegel's crosstool.
- built u-boot-1.0.1 and flashed it to the board using BDI2000
- built linus-2.4.22, (with the below mentioned patch on last attempt).

The compilation goes through fine, I get "vmlinux" on the top-dir, and also
a vmlinux.gz in the arch/ppc/boot/images if I do a "make zImage".

When I configure bootp, and bootup the board, u-boot comes up fine, the tftp
download of the kernel image goes through fine too. Then I am stuck with a
"Bad Magic Number". Some initial digup led me to a mismatched image header
magic number.

Could anyone please help me with how to go ahead? Am I missing something?

Also thanks to everyone whose postings on this and other lists helped me get

You will need to apply the corresponding linuxppc patch
(/pub/linux/kernel/ports/ppc/2.4) to 2.4.22. The zvmlinux doesn't seem
to be built with only 2.4.22.
