You are assuming that the kernel 'stops short of loading'. It is quite likely that the kernel has gone along a fair but and attempted to bring up your board but has panicked at a very early stage before the kernel log buffer was flushed to the console thereby preventing you from getting a feel for what really went wrong. There could be any number of reasons for this of course.

My recommendation would be to start hacking the kernel from a very early stage of initialisation. If you can get to Linux's '__log_buf' and print out the ASCII contents straight to the UART, I bet you'll get a handle on the problem. It'll most likely be a kernel misconfiguration issue but you'll get the idea one hopes.
