Can't suspend to ram, since linux3.11 and more

[xzu]

I can't suspend to ram since linux 3.11, with ubuntu12.04. Older version (3.8, 3.5 etc..) suspend perfectly.
So, I can't suspend with ubuntu 14.04 and 16.04. :(

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.7 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Note: for most of kernels tested, the suspend seem to work, the screen turn blank and cpu fan seem off, but the CD drive make a noise (same as when I boot) and then the system resume (with certain kernels, there is no way to resume).

With 4.7:
the login screen is a little strange: the mouse cursor flashes quickly, but then I can get the login normally.
Unfortunately, the suspend seem to work (no auto-resume) but in fact the system is not suspend, the CPU fan is still running (and the led indicate PC is on, not sleeping).
:/

[xzu (xzurukneg)]

I'll test 3.5 kernel (suspend working with ubuntu12.04) for fun.

Please tell me if I can do something to help to resolve this issue, I'm still running 12.04 just because of that!

[xzu (xzurukneg)]

With "sudo pm-suspend" the system quickly auto-resume (nearly nothing happen).
No terminal output.

[penalvch (penalvch)]

xzu, the next step is to fully commit bisect from kernel 3.8 to 3.11 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit bisecting.

Also, the kernel release names are irrelevant for the purposes of bisecting.

After the offending commit (not kernel version) has been identified, then please mark this report Status Confirmed.

Thank you for your help.

[xzu (xzurukneg)]

Please consider all this take time, and I also need to find workaround, and work to live.
Sorry for delay, I'll do this, but can't certify when.

[xzu (xzurukneg)]

Found it.
So with ubuntu 12.04:
ii linux-image-3.10.103-0310103-generic 3.10.103-0310103.201608311738 Linux kernel image for version 3.10.103 on 64 bit x86 SMP
=>suspend works

ii linux-image-3.11.0-031100rc1-generic 3.11.0-031100rc1.201307141935 Linux kernel image for version 3.11.0 on 64 bit x86 SMP
=>suspend don't work

Exactly the same symptoms as with other later kernels, with ubuntu 14.04 and 16.04.

[xzu (xzurukneg)]

Is this enough? (not sure to understand the total process)

[penalvch (penalvch)]

xzu, have you had a chance to fully review https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1606178/comments/7 ?

[xzu (xzurukneg)]

I'm just a musician, not computer scientist.
All that seem quite "advanced".
Can you tell me what you're waiting for with your words.
English is not my own language, maybe reading you will help me to understand what is needed to do.
Anyway, any help welcome.

"After the offending commit (not kernel version) has been identified" => I don't get the sense of that. What do "offending commit" means?

[xzu (xzurukneg)]

I finally found some help from a friend and he explain me what you're waiting for. I think I'll can do that (or we), but that will take time. Can't tell when.

[xzu (xzurukneg)]

I'm supposed to bisect this week.

[xzu (xzurukneg)]

Well, someone help me and we finally don't do the bisect:
all I can say: the problem comes with the 3.11.0-031100rc1.201307141935 Linux kernel image for ubuntu kernel release.
We don't find the main kernel corresponding, and we esteemed that will be a very to big work for no guarantee.

So we try to find a solution with 16.04, because the goal of all this is to suspend with an higher kernel than 3.10 with my hardware.

We found it by first do:
 -disable usb wake up ( cat /proc/acpi/wakeup to check what is enable)
 -then, I need to first do sudo pm-suspend in the session. If I don't, I can't resume.
If I do first sudo pm-suspend in the session, then I can resume normally.
So I need to do this if I reboot.

So workaround found, this thread can be closed!
