Theo, What is your uncompressed kernel size with all the extra stuff you added to the initramfs. u-boot puts itself at 16MB of DDR. The kernel is copied to DDR at 7MB compressed and then is uncompressed at ~0MB. If your kernel is too large uncompressed it can overwrite the compressed uImage (that is being uncompressed), or if it is really large it can overwrite u-boot itself. If your uncompressed kernel is > 7MB you might want to change the address in DDR that the kernel is copied to. Perhaps something like 32MB.
