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

Title:
5-10 second delay in kernel boot
Status in linux package in Ubuntu:
Confirmed
Bug description:
In Trusty I see a big delay while the kernel boots that I did not see back in
Precise.
Some people have been experiencing this in Saucy too, so I don't know exactly
when it started happening.
Excerpt from dmesg:
[ 3.740100] Switched to clocksource tsc
[ 14.208118] PM: Hibernation image not present or could not be loaded.
[ 14.208885] Freeing unused kernel memory: 864K (c19ac000 - c1a84000)
The exact messages above don't matter, they are different on different boots
or on different machines.
It even happens with e.g.
$ sudo kvm -m 768 -cdrom trusty-desktop-i386.iso
My current kernel is
Linux server 3.12.0-7-generic #15-Ubuntu SMP Sun Dec 8 23:42:09 UTC 2013 i686
i686 i686 GNU/Linux
...but the exact version, maybe from 3.8 to 3.12+, shouldn't matter, just run
`dmesg` yourself and check if there's a big delay there.
