Hi
seems we meet different errors.
I will try to enable the "Built-in kernel command line" and try again

Linux version 2.6.37.6 -->Linux version 3.0
Linux version 3.0 -->Linux version 2.6.37.6
the screen stop after exec 'kexec -e', no more message
more info about this may relate to

Linux version 3.0 -->Linux version 3.0
the screen keep output kernel message. end with:
Kernel panic - not syncing VFS: Unable to mount root fs on unknown-block(0.0)
