That is a fundamental issue with the build of the kernel
itself. IE, something fundamentally wrong with the image.
u-boot uncompressed it, then jumped to it, and it crashed
hard.

Woah back up. zImage? I'm not sure what the difference
is but I use the uImage to boot the kernel.

Probably the setup of mkImage is wrong, kernal being loaded
in the wrong place in memory, etc or the machine type being
passed to the kernel is wrong?
PS: I can send you a known working uImage and zImage for
the AT91RM9200EK that you can try. Just maybe not today
as it's Christmas.
