This all matches what I used in my local test (except for the
CONFIG_MODULE_DECOMPRESS which was disabled).  So I still don't
understand what's special about your configuration that results in the
failure.

Could you please send:

- The *complete* kernel config that you were using (before enabling
CONFIG_MODULE_DECOMPRESS).

- All the error messages from the initramfs when using this kernel and
initramfs-tools 0.146.  (A photograph of the screen is fine, if it's
readable.)

Ben.
