["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Brian Murray / Chris J Arges, this bug was reported a while ago and
there hasn't been any activity in it recently. We were wondering if this
is still an issue? If so, since this was reported, there has been
considerable work done in drivers/misc/mei/* addressing a plethora of
watchdog issues. Would you mind testing for this with the latest
development release of Ubuntu via http://cdimage.ubuntu.com/daily-
live/current/ and advise on if this issue is reproducible?

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
