Julien Aubin, the next step is to bisect between Precise and Quantal, in
order to identify the offending commit. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Title:
  Driver for hdd Western Digital Caviar Black 500 GB / 1 TB prevent
  suspend

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  This bug is actually related to bugs 1057664 and 1171560, and is an
  upstream bug.

  When I suspend my system to RAM, actually suspend does not work and
  instead I get a blinking cursor, and after some time system turns back
  again.

  After some debugging, I've found this within the logs of dmesg :
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1181878/+attachment/3744189/+files/dmesg

  The command sent to trigger these logs was :
  echo 'mem' > /sys/power/state
  With pm-suspend they do not appear.

  On my system, devices sda and sdc actually point to HDDs WD Caviar
  Black with firmware 05.01D05. sdb and sdd point to other HDD models,
  not these ones. And it turns out that I get errors with these specific
  devices, sda and sdc. The bug is not always reproducible, sometimes
  suspend goes well, but sometimes it doesn't. I suspect there's
  something wrong with the commands sent to these devices.

  The bug started to be reproducible with Ubuntu 12.10, prior to this
  while I already owned these HDDs. The HDDs themselves are not culprit
  as the suspend command works on MS Windows 7. And my configuration is
  also not culprit as I tested with a raring liveCD and the result is
  the same.

  I don't know who must be contacted in the kernel team in order to look
  at this issue, if you could indicate me who this would help.

  WORKAROUND: - Run as root :
  echo 0 > /sys/power/pm_async

  (added to /etc/rc.local to be permanent)
