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

Seeing this here as well; the messages also go to dmesg, and don't seem to affect anything, so it would be really nice to not have these marring the screen on resume.

And note, for reference, that they pop up another set as /part of/ the resume.

If you updated the kernel you likely rebooted so the messages were
cleared. The messages accumulate for each suspend and resume between
reboots.

I have this problem and it often seems related to instances when I am unable to resume at all.

This problem still exists on Precise 12.04.2 64bit with Linux 3.2.0-38. Will the fix from upstream (August 2012) be applied to the Ubuntu kernel?

Joseph Salisbury (jsalisbury) wrote :

@Andre,

Can you test the latest 3.2 stable kernel:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2.39-precise/

That will confirm if this fix is in the upstream stable kernel. If it is, then the fix will make it's way into Precise through the normal stable update process.

Andre (ajx) wrote :

@Joseph, I tested the latest 3.2 stable kernel (3.2.39-030239). It did not fix the problem.

However, I discovered a workaround, which does (maybe it introduces another problem I am not aware of?): I blacklisted 'mei'. I added

blacklist mei

to

/etc/modprobe.d/blacklist.conf

Now I do not get these errors anymore, no matter if I use 3.2.38 or 3.2.39.

I found this workaround here:
http://ubuntuforums.org/showthread.php?t=1970325

Does this help to fix the problem for all users of Precise?

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?

This (or something very much like it) still occurs in relation to failing resume from suspend on my Dell T7600.

watchdog complaint is echoed to tty and resume fails.

This is on an up to date Ubuntu 12.04, and has affected the last few kernels (a few months I think, but haven't kept the old ones so can't easily test when it was introduced)

blacklist mei workaround seems to help so far on this kernel. New kernel just released, will test that one too.
