TI Kernel update hang

Hi,

I have two pretty much identical blacks that I regularly update using the update_kernel.sh script.
Have just updated from v3.14.35-ti-r56 to v3.14.37-ti-r57. The first bone rebooted as normal, whereas the
second now hangs (output from serial console), anyone any ideas what might have gone wrong?

Looks like things went off the edge ^^, lets first look at uEnv.txt
and double check:

loadaddr=0x82000000
fdtaddr=0x88000000
rdaddr=0x88080000
