What was the issue? What was the fix?

The kernel's bundle_initramfs task depends on
${INITRAMFS_IMAGE}:do_image_complete, so if the new value you set for
INITRAMFS_IMAGE is an image which had previously been built the
kernel's bundle_initramfs might not get triggered again?
Perhaps try running "bitbake -c cleansstate" for your image and then
"bitbake linux" again.

A kernel image without the bundled initramfs is always going to be
built as part of the normal build process for the kernel (it's built
by the kernel's compile task - the version with the bundled initramfs
is built by the bundle_initramfs task).
Normally you should be able to tell the difference between the two
kernel images by the .initramfs suffix, however the bug you saw
originally was in the bundle_initramfs code to do that renaming, so
depending on how you resolved the original issue, maybe your kernel
images are still getting mixed up?
