Lenovo helix 2nd gen does not wake up from suspend

[Johan Bernhardsson]

Using a fresh install of ubuntu 15.10. When the laptop enters suspend it wont wake up. Not from trigging the lid switch or pressing the power button.

Using Latest kernel 4.2.0-22-generic. Tried with two different bios versions to rule out bios.

The only option is to press and hold and do a new cold start.

Johan Bernhardsson, thank you for reporting this and helping make Ubuntu better.

At your earliest convenience, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue.

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

[Johan Bernhardsson (smallone)]

Tested and added the tags. The bug still exists in 4.4-rc7

When i suspend the laptop it refuses to resume. Only a cold boot works. Lid switch does not respond. Nor does the power button.

[Johan Bernhardsson (smallone)]

https://bugzilla.kernel.org/show_bug.cgi?id=100171

This looks like the same thing upstream.

[penalvch (penalvch)]

Johan Bernhardsson, could you please provide the missing information from https://wiki.ubuntu.com/DebuggingKernelSuspend ?

[Johan Bernhardsson (smallone)]

so i have tried with pm-suspend, suspend from gnome3 and suspend on inactivity. All results in a laptop that i cant wake up with lid switch or power button.

I attached wakeup and dmesg.txt from the latest attempt. Debugging with pm_trace reset the systems time.

From dmesg.txt

[penalvch (penalvch)]

Johan Bernhardsson, unfortunately, that didn't provide the root cause.

However, a newer mainline kernel has been released (4.4) and the suspend article has been updated.

Hence, could you please test with the latest kernel and provide all items of information?

[Johan Bernhardsson (smallone)]

I will try 4.4 right away and see if it helps.

[Johan Bernhardsson (smallone)]

I tried 4.4 and the bug is still there. And the debug doesn't reveal anything more than before.

[Johan Bernhardsson (smallone)]

I have tested 4.4 and looked around to see if i can find something more usefull. It appears that lenovo carbon x1 might have the same problem (not confirmed yet tho)

[Johan Bernhardsson (smallone)]

A did a test to see if freeze would work. And it does work better than suspend. Only snag is that it only works with a keyboard connected as the keyboard is the only way to wake it up. The power button is still not activating anything

[Johan Bernhardsson (smallone)]

tried 4.5 rc2 bug is still there

[Johan Bernhardsson (smallone)]

Using linux 4.5-rc5. same result.

    2.259205] Magic number: 1:0:0
[ 2.259260] memory memory48: hash matches

And pm test gave me that.

[penalvch (penalvch)]

Johan Bernhardsson, to advise, that little piece information provided is not terribly helpful.

Despite this, you would to perform a memory test to confirm you don't have bad RAM.

If this test passes, then you would want to review the recently updated suspend debugging article https://wiki.ubuntu.com/DebuggingKernelSuspend to fully confirm which driver module is at fault here.

[Johan Bernhardsson (smallone)]

pm test none failed. The laptop went to sleep and never woke up.

memory48 hash matches when booting up again.

it seems like there is some special thing with lid and power button when it comes to wakeup

One difference i see is that my samsung laptop has PWRB on S5 and not S0 and that my asus has sleep btn on S4 and not S3.

This laptop doesnt have a sleep button on the chassi nor on the keyboard btw.

Are you saying that none of the pm tests failed?

[Richard Trabing (richtrabing)]

Hi, I just wanted to keep this thread alive, as the bug seems still to be present. I recently tried suspend with the Helix 2 and Ubuntu 16.04 and can confirm the same behaviour.
This issue is being tracked on the kernel bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=100171
There was a BIOS Update released by Lenovo on the 25th of May which addresses some Suspend issues for Windows 10. I haven't yet checked my BIOS version- will check tonight.
If it is still an issue, I will post logs and DebuggingKernelSuspend results...

[penalvch (penalvch)]

Richard Trabing, it will help immensely if you filed a new report with the Ubuntu repository kernel (not mainline/upstream) via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.

For more on why this is helpful, please see https://wiki.ubuntu.com/ReportingBugs.

[Richard Trabing (richtrabing)]

Thanks for your quick feedback, Christopher. I'll do what you suggest. Am new to this Bug reporting process, but the documentation looks good.
I am assuming that by submitting a new bug report that I will be getting a new bug number. I'll attach that one to this thread once done.
I checked my BIOS version this morning and I am on the latest - 1.86 (dated 2 May 2016, I think). So, in summary, Ubuntu-Gnome is unable to resume after a normal power button suspend (or lid-close suspend) on the Lenovo Helix 2 with the latest BIOS version.
(By the way, you guys are doing great work. Love the latest Ubuntu-Gnome!)
