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.
