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. -- Pali Rohár pali.rohar@gmail.com
