[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Wong Yong Jie (yjwong)]

I see this during suspend/resume, and sometimes it results in lockup, requiring a restart of lightdm.

I think it might be safe to say that this regression happened somewhere between Linux kernel 3.13 and 3.16. I was previously running Ubuntu 14.04 LTS (with the 3.13 kernel) and there were no issues. However, running Ubuntu 14.04 LTS with the upstream 3.16 kernel gave this warning. After upgrading to Ubuntu 14.10 LTS (with the Ubuntu 3.16 kernel), the problem persisted.

[DavidJB (davidjb)]

What looks to be the same issue affects my Ubuntu 14.10 install on my MacBook Pro 10,2. The screen locks up, but the mouse is able to be moved and seen moving, and interacting with windows and desktop elements is stlll possible (eg if a video is playing with VLC, can press Space to pause and resume and hear audio), though because they are 'frozen', no visual changes happen.

After about 5 minutes or so, I'm able to continue using the computer without issues. I switch TTY during the 'freeze' and the screen remains blank for the period, and when the login console appears, I can switch back to TTY7 and continue using my graphical session, no restart of anything required.

For what it's worth, output of dmesg:

Ack, sorry everyone, I changed the status to "Fix Released" by accident and now I can't change it back to "Triaged". Can someone change it back?

[peterthevicar (peterthevicar)]

I just tried with the Vivid kernel (3.18.0) and had the same error. I needed to restart lightdm to get things going again.

[John Baptist (jepst79)]

Is there an upstream for this bug?

[Øyvind Stegard (oyvindstegard)]

Same issue on Dell E7440 (Intel HD 4400 Haswell) running Ubuntu 14.04 with upgraded kernel 3.16 (LTS enablement).

[Øyvind Stegard (oyvindstegard)]

Actually, I seem to be getting these kernel warnings every time display comes back from DPMS sleep, and not only resume from suspend.

[Øyvind Stegard (oyvindstegard)]

Although not upstream, this looks like the Redhat/Fedora bug for the same issue:
https://bugzilla.redhat.com/show_bug.cgi?id=1120901

[Kyle Barbour (kylebarbour)]

I'm also having this issue on a new Lenovo X1 Carbon generation 3 (model 20BS CT01 WW). The screen will go black at random intervals and a similar stacktrace is produced on dmesg. Switching to a TTY and back (ctrl+alt+F1 and then back to ctrl+alt+f7, for example) returns to a functional Xorg. This is on Ubuntu trusty 14.04.3 LTS and 3.16.0-46-generic #62~14.04.1-Ubuntu.

[Kyle Barbour (kylebarbour)]

Unfortunately, I've recently found that switching to a TTY doesn't always work, and sometimes the screen remains black no matter what is done and a forced reboot is required.

[Øyvind Stegard (oyvindstegard)]

I cannot be 100% certain, but I am reasonably sure this particular problem has vanished for me after I upgraded to the latest LTS enablement stack (kernel 3.19 and newer Xorg components from vivid). I still see some suspend related traces in kernel log, but they are not the same, and in practice I experience less issues.

https://wiki.ubuntu.com/Kernel/LTSEnablementStack

[Kyle Barbour (kylebarbour)]

I've migrated to the LST Enablement Stack and after a few days agree that this seems to have been resolved with the newer kernel and xorg components (although it's hard to know for sure - on the 3.16 kernel I think I would have had a problem by now, however).

That's for 3.19.0-26-generic #28~14.04.1-Ubuntu on Ubuntu 14.04.3 LTS. Steps to resolve issue were simply:

$ sudo apt-get install --install-recommends linux-generic-lts-vivid xserver-xorg-core-lts-vivid xserver-xorg-lts-vivid xserver-xorg-video-all-lts-vivid xserver-xorg-input-all-lts-vivid libwayland-egl1-mesa-lts-vivid linux-signed-generic-lts-vivid

and reboot (see instructions in link provided by Øyvind Stegard).

[Vadim Zaliva (lord-5)]

I think I am having the same problem on Thinkpad x260. It hangs up during suspend and last message in syslog is:
