@penalvch: as I mention in comment #6, the "kernel-fixed-upstream" tag
is not appropriate because this was never an upstream bug, so nothing
was fixed upstream. It's an ubuntu-specific bug, so upstream is not
related at all to this bug and shouldn't appear in any tags.

The "needs-kernel-logs" tag also isn't appropriate because it's useless
information, anyone willing to work on this can just check the logs on
his own pc.

Karma points are nice, but they shouldn't be a goal... If you really
want to help, do so by triaging bugs, not by tagging them...

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.
