Hi Mat,

This is not so weird, you probably need to find the correct entry point for the kernel you've built.

You can find it with the following commands (please adapt it to your environment):

# cd /your/current/build/sources/
# make ${MAKEFLAGS} kernel-toolchain
# make ${MAKEFLAGS} buildenv
Entering world for mipseb:mips
# nm /data/tftpboot/ar7240/boot/kernel/kernel | grep " _start"
80050100 T _start

So in this case i need to load the load the kernel at 0x80050000 and then start it with 'go 0x80050100'. (this kernel was built with KERNLOADADDR=0x80050000: http://pastebin.com/A1d06Eqe).
