just released, will test that one too.

Title:
  Upon resuming from suspend messages appear in tty

Status in The Linux Kernel:
  Fix Released
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  With every resume from suspend I briefly see the following in a tty
  before the display is switched to X and my screensaver:

  Apr 17 08:33:45 localhost kernel: [  256.610821] watchdog: only one watchdog can use /dev/watchdog.
  Apr 17 08:33:45 localhost kernel: [  256.610826] watchdog: error registering /dev/watchdog (err=-16).
  Apr 17 08:33:45 localhost kernel: [  256.610829] mei: unable to register watchdog device.

  This accumulate so that on the 2nd resume from suspend I will see the
  previous messages and another one for a total of six lines.  I believe
  this is a recent development and started happening with the 3.2.0-22
  kernel.

  == WORKAROUND ==

  Blacklist the mei module
