[Bug 1259861] Re: 5-10 second delay in kernel boot

 

I just tested with linux-
image-3.13.0-031300rc3-generic_3.13.0-031300rc3.201312061335_i386.deb,
it doesn't happen there.

I don't think I should put the 'kernel-fixed-upstream' tag as the
problem might be in some Ubuntu-specific kernel patch or configuration
option that's been around for a couple of years.

Do you want me to test with the vanilla 3.12 too? The delay probably
won't exist there either...

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.
