You must use the raw  kernel  image,  without  the  kernel  bootstrap
stuff.  And  you  must  make  sure  to  pass the parameters correctly
(struct bd_info). See also the FAQ at

This is probably the problem.

This is probably not enough. At least  you  must  make  sure  not  to
include any bootstrap stuff.
