Basic questions like this on a vendor-specific kernel (and a
"procedure defined by HHL") might be better answered by contacting
your vendor's support arm.

I have no problem with initrds using a ramdisk.image.gz created via
"dd if=/dev/zero ...", mke2fs, and populated via a loopback mount.
Looks like you have ramdisk size set properly...make sure the
filesytem (ext2) is built-in.
