The initrd= part should not be necessary (assuming that  your  kernel
knows  how  to  pick up a ramdisk from flash; this has been discussed
here several times before, search the archives if necessary).

So your kernel does not know how to handle this. Fix it.

I've posted the required patches several times  before  (or  see  the
