Comment 22 for bug 1259861

I have uploaded some modified initramfs-tools packages to my PPA:

https://launchpad.net/~rhansen/+archive/ubuntu/bug1259861

With the version in my PPA, the initramfs init script now has a new
initramfs_ip parameter in addition to the existing ip parameter. The
initramfs treats the initramfs_ip parameter the same as the ip
parameter. Using initramfs_ip=* instead of ip=* avoids the 12 second
kernel delay that comes from the kernel processing the ip=* parameter.

To eliminate the boot delay:
  1. run:
         sudo apt-add-repository ppa:rhansen/bug1259861
         sudo apt-get update
         sudo apt-get dist-upgrade
  2. edit /etc/default/grub and change your ip=* argument to
     initramfs_ip=*
  3. run:
         sudo update-grub
