You appear to have loaded your kernel, but provided no command line
arguments.  At that point the kernel should load and execute, provided
it is a valid file, which the size and type information appear to
validate.

Perhaps the kernel you are trying to load is broken, of the wrong
system (target) type, or requires arguments?

I suggest recovering via some kind of rescue cd and attempting to
repair any potential issues inside of a chroot do your root
filesystem.
