If you have a serial console you can probably get output on that. If you
have flipped EMBEDDED to Y then you might also have to enable
EARLY_PRINTK. Another trick might be to turn set
BOOT_PRINTK_DELAY (Kernel hacking -> Delay each boot printk message by N
milliseconds) to something like 2000 and see if you can read/catch the
messages before the kernel reboots...

Failing that start a git bisection (
http://www.kernel.org/doc/local/git-quick.html#bisect or
http://www.stardust.webpages.pl/files/handbook/handbook-en-0.3-rc1.pdf )
from the last good kernel...
