Bug Description

After hibernating the system and than resuming it the system reboots notifying that it is resuming and than stops/freezes. The system does not respond to anything (no tty's other notifying textg are available).

After booting kernel 4.10-042 the hibernation and hibride hibernation/sleep functions as proposed.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1743094

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Can also confirm that 4.13.0-26-generic causes the computer to fail to resume from hibernation. Downgrading to 4.10.0-42-generic fixes the problem.

Computer: Dell XPS 13 9360
BIOS: 2.5.0

When attempting to resume from hibernation, the LUKS password prompt is displayed, but the screen goes black immediately after entering the password. The Caps Lock key does not work, so I assume the kernel hangs. After leaving the computer for ~30 seconds, the fans begin to run at full speed.

I'm experiencing the same problem with kernel 4.13.0-26-generic, 4.10 series works fine.

Specs:
Intel i7-6700k (using intel-microcode 3.20180108.0~ubuntu16.04.2)
16 GB RAM, 4 GiB Swap
NVidia GTX 970 (nvidia-384.111-0ubuntu0.16.04.1 drivers)

If I knew how I might be able to bisect. I found some info on the issue (see links), I think I can compile a kernel if I knew the options that the kernel I used was compiled with. I'm not really a programmer so if I have to read through (too much) code I will fail. Is there a link for Ubuntu standard kernel compiling?

I understand from Dirk Bachmann that some where between 4.13.0.21 en 25 thinks got broken. I understand that I need the first kernel that broke and the one before and somehow have to compare them with git. At least I should be able to find out at what update things got broken.

How can I successfully run the script "git bisect run" step by step if I have to hibernate the system and each time I do this the system will freeze at resume? I assume the analysis will be aborted each time.

If someone has a link to some more info (for a not really programmer), I'll give it a try.

Same issue here: when trying to resume from hibernation, my laptop screen stays black and I have to force kill it.
Been scrolling through the logs, but there seems to be no data between when I started hibernation and after I restarted my laptop after the force-kill.

Christian Sarrasin (sxc731) wrote :

Same issue here, fresh install of stock Ubuntu 17.10(.1) on a ThinkPad X1 Carbon gen5, kernel 4.13.0-25-generic, with LUKS-encrypted swap partition sitting alongside the root partition. The same hardware/setup worked fine on Zesty but as we know, that just went EoL.

Just to add: the machine seems completely frozen at resume based on the keyboard caps-lock LED test. I do get the LUKS password prompt so that part seems fine.

Hibernation is critical functionality from a security standpoint as an alternative to far less secure suspend to RAM functionality.

Please let us know how/if we can help progressing this bug.

Same issue with a Lenovo W520 on 16.04.3 LTS with 4.13.0-26. The quite fresh 4.14.13 kernel (Canonical Kernel Team PPA) solves this "resuming from hibernation" problem. I agree that this is a very important bug that should be solved soon.

I can also confirm that with 4.13.0-30, hibernate did not work, but installing 4.14.13-041413-generic works perfectly.

Resuming starts but after a few seconds screen goes dark and nothing can be done except forcing off the laptop.

Also found "Hibernation image not present or could not be loaded" in kernel log.

Looking at Dirk Bachmann's comment #23 I did a:

gitlog Ubuntu-4.13.0-18.21..Ubuntu-4.13.0-25.29

That shows the major changes are the x86/mm PTI patches to address the Meltdown issue.

Dirk: can you boot 4.13.0-25 with the kernel command-line option "nopti" and do your hibernate/resume tests and report back?

- Ubuntu xenial 16.04.4

While it's being bug fix, i have disabled hibernate on Ubuntu.

I had the same issue. Expecting someone to fix it, but still none update.

right now I have to use 4.10 to have resume work

Iain (strawp) wrote :

I've been following this for a while. 16.04 isn't going to get the 4.15 kernel until August (https://wiki.ubuntu.com/Kernel/Support) but 18.04 is going to ship with it (https://wiki.ubuntu.com/BionicBeaver/ReleaseNotes) and that gets a stable release on 26 April.

I think everyone has the option of one of three things:

1. Do ibrokeit's guide on how to use the mainline 4.15 kernel (and be unsupported but apparently have hibernate working again)
2. Wait for a month for 18.04 to come out and then upgrade, getting a supported 4.15 kernel with it and presumably working hibernate
3. Wait until August for 4.15 to be included in 16.04

Personally I've put up with no hibernate for a couple of months already so I'm just going to wait for 18.04 (which I was going to upgrade to anyway) rather than risk the stability of my work machine, however small that risk might be.

Maurice (mak-5) wrote :

Hi Lain, thanks for summing things up. It's a pity that we will have to wait until August to get this issue fixed in 16.04.

I've been living without hibernate for a couple of weeks now and HATE it.

I still hope some patch emerges isolating the issue and this patch gets backported to 16.04....

Hello - I'm unable to reproduce this bug because I can't use hibernation on my system but I may have spotted the problem while fixing a different bug. Could someone that's still affected by this bug, when using the 4.13.0-38.43 kernel, please try out the test kernel that I built here:

  https://people.canonical.com/~tyhicks/lp1743094/artful/

Please report back if the test kernel fixes the problems that you were experiencing on resume. Thanks!

Hi Tyler, I just tested it on my PC.For me, the problem persists. My computer still freezes on resuming. Switched back to 4.10. thanks.

Tyler Hicks (tyhicks) wrote :

Thanks for giving it a try. I'm disappointed that it didn't fix the issue for you.

I'd appreciate it if at least one more affected user could give the test kernel a shot to help rule out the chance of multiple bugs being involved.

This is still a problem in bionic as well. I just did a clean install on a workstation which exhibits the problem, but I also have a laptop which was upgraded from 17.10, which has not ever exhibited the problem.

I've attached lshw output for the two machines (inara is the machine for which suspend/resume works, vera is the one that doesn't)

Hmm, in a somewhat disheartening turn of events, I thought I'd try installing the nvidia proprietary driver on my workstation (that's what I had installed on 16.04, when suspend/resume worked). ...And now, suspend/resume works perfectly (and quickly) on the workstation. So maybe this is a nouveau bug? Is everyone else having problems using nvidia graphics hardware with the nouveau driver?

Intel on Entroware laptop for me so hardly a driver problem (but maybe not even the same bug)
efficient diagnosis procedure welcomed.

I have Nvidia graphics and I am using the Nvidia drivers so it isn't just a nouveau driver problem. But it may be worth re-installing the nvidia drivers again to see if that solves the problem for me.

Re-installing the nouveau and nvidia drivers didn't work for me sadly. The problem persists.
