You can try to regenerate initramfs with ubuntu command:
$ sudo update-initramfs -u -k all
In case you modified or updated some initram files or kernel modules you
need to regenerate it to take effect at boot... -k all tells to
regenerate *all* initramfs images, not only for currently booted kernel.
