Description Matt Schepers 2015-09-18 18:13:37 UTC
[1.] One line summary of the problem:

Kernel does not 'hibernate' system or write memory image to /swap file during 
hibernate.
    



[2.] Full description of the problem/report:

When hibernating the system by using systemd 'systemctl hibernate' OR by setting kernel variables in '/sys/power' directly the kernel fails to complete the hibernate sequence and write the memory image to swap 30-60% of the time. Sometimes it is completely successful. Before each hibernate I have simulated hibernate successfully using the guide posted here: https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt

Upon wakeup there is something written to the swap file, but the machine is unable to resume from it. Logs indicate that the hibernate process does not complete and the image is not written successfully.

Additional details provided in this bug report and output from journalctl.

journalctl -xe -b -2 | grep 'habanero kernel\|CUSTOM'




[3.] Keywords (i.e., modules, networking, kernel):

power management, hibernate, kernel




[4.] Kernel version (from /proc/version):

Linux version 4.1.6-201.fc22.x86_64 (mockbuild@bkernel02.phx2.fedoraproject.org) (gcc version 5.1.1 20150618 (Red Hat 5.1.1-4) (GCC) ) #1 SMP Fri Sep 4 17:49:24 UTC 2015




[5.] Output of Oops.. message (if applicable) with symbolic information 
     resolved (see Documentation/oops-tracing.txt)

Attached.
journalctl -xe -b -1 | grep 'habanero kernel\|CUSTOM' > journalctl.output.txt




[6.] A small shell script or example program which triggers the
     problem (if possible)

Shell script 1 to reproduce this issue:
#!/bin/bash

logger 'CUSTOM: starting CORE pm_test'
echo core > /sys/power/pm_test
echo shutdown > /sys/power/disk
echo disk > /sys/power/state

sleep 2
logger 'CUSTOM: disabling CORE pm_test'
echo none > /sys/power/pm_test

logger 'CUSTOM: hibernate for real.'
echo shutdown > /sys/power/disk
echo disk > /sys/power/state

Shell script 2 to reproduce this issue:
#!/bin/bash

systemctl hibernate

Comment 1 Aaron Lu 2015-09-21 02:42:06 UTC
Are there logs when problem occured?
Comment 2 Matt Schepers 2015-09-24 02:15:05 UTC
Hi Aaron,

Appologies for the late reply - I've been out of town. I was able to
reproduce the problem again by hibernating and resuming repeatedly.
I've attached the journalctl -b -1 output here. If there is a better
log let me know.

Looking at the journalctl output it was originally unclear to me where
the problem was too, so I wrapped my system's hibernation command in a
shell script that would also output to the log when the script was
called.

---------
#!/bin/bash
logger 'CUSTOM: Starting hibernate!!!'
systemctl hibernate
---------

As you can see from the journalctl output the hibernate script called
several times and the system hibernates and resumes successfully each
time. The last time the script is called the kernel doesn't seem to
pass information to the log about freezing processes, shutting down
hardware etc. However it still powers off the machine as if it were
really hibernating. Upon resume the kernel tries to read an image from
disk after the encryption password is given, but fails and leaves me
with locked up hardware and a black screen. I'm assuming there are no
logs from the resume process because of the encryption, but I don't
know.

Does that better describe the issue? I just updated to the 4.1.7
mainline kernel and it has the same issue.

There is someone on the arch user forums that appears to have the same
issue with the same machine here:

https://bbs.archlinux.org/viewtopic.php?id=201990

His logs seem to show the same kind of failure that mine do.


Thank you for getting back to me!

-Matt

Yes, that's clear now. So the log we want to see does not exist :-(

And about encryption, what is it? Can you please elaborate this? Thanks.

Is there a way to live-debug the kernel and get its output(I could do it if you show me the docs)? How about a debug dump to /boot?


> And about encryption, what is it? Can you please elaborate this? Thanks.
FDE using LVM and LUKS. This is the setup I've got: 
https://wiki.archlinux.org/index.php/Dm-crypt/Encrypting_an_entire_system#LVM_on_LUKS
Comment 6 Aaron Lu 2015-09-24 06:10:13 UTC
Not familiar with encryption, I guess kernel has no knowledge of the encryption? In other words, is the encryption entirely supported from user space?

I doubt the resume failure have something to do with the encryption, possible to test without encryption setup?
Comment 7 Hemant Kumar 2015-09-24 12:07:36 UTC
I am the other user who have reported this problem on Arch. forums. 

Aaron - what logs exactly you are looking for? I have pasted output of journalctl here - https://bbs.archlinux.org/viewtopic.php?id=201990 but obviously you have seen that. Is there a document somewhere that describes how to create useful logs for debugging hibernate?

FWIW this problem indeed has nothing to do with encryption. I am not using encryption and I see this problem often (not always though). Whenever hibernate/resume fails - the hibernate image is not written to disk properly and "PM: Syncing filesystems ... done." is missing from logs.

Thanks again for looking into it.
Comment 8 Matt Schepers 2015-09-24 14:28:20 UTC
Aaron and Rafael, is there a way to redirect the kernel's debug/log output to a file on /boot or a USB drive? I would be happy to reproduce this again to generate that output.

Logs that have error messages.
But obviously in your cases, when the error occurs, the log will not be properly written to disk.
Serial log is helpful, but that isn't possible for laptops.

I didn't, but I assume that is sort of the same as shown in comment #1, which says the hibernate and resume is successful for several times and unfortunately successful logs are not helpful for debugging.

Good to know this, thanks.
One thing to make sure: is your lapop the same as Matt's? I need to make sure we are dealing with the same problem in this bug.

> hibernate/resume fails - the hibernate image is not written to disk properly

Do I understand this problem correctly that:
1 It happens sometimes, but not usually the first time;
2 It happens at hibernation phase, instead of resume phase;
3 This occurs with a swap file, instead of a swap partition;
4 This occurs with or without using encryption of the disk partition.

Thanks.

> 3 This occurs with a swap file, instead of a swap partition;

I am using swap partition (of size more than double the amount of RAM I have). Here is my kernel boot parameter looks like:

root=UUID=4a63e4a9-d35a-4c0b-8a08-c80a418e98bb rw resume=UUID=be708e5c-2fc7-41f4-ab28-8b2ac565516e i915.enable_ips=0

Also, I am using Thinkpad T450s, I am not sure which system Matt is using but looks like a Thinkpad.

It is the same machine. I have a lenovo t450s as well.


> Do I understand this problem correctly that:

Correct.

> 2 It happens at hibernation phase, instead of resume phase;
I believe this to be true, but am not qualified to say for sure. The logs do not show information from the kernel showing successful freezing of processes and hardware WHEN it occurs.

> 3 This occurs with a swap file, instead of a swap partition;
I have a swap partition. This occurs for me with the swap partition implementation. I have never tried a swap file, the way I named the thread was ambiguous. Sorry!

> 4 This occurs with or without using encryption of the disk partition.
It appears so. He has no encryption, but I do.

Patch to workaround panic during resume from hibernation

This patch is to work around the panic during resume from hibernation.
I think we can boot system with init=/bin/bash, and compile disk driver as build in (CONFIG_SATA_AHCI=y for example), then after first booting into the system,
try:
swapon /dev/sda3 (your actual disk partition, not uuid please)
the echo disk > /sys/power/state,

then append resume=/dev/sda3 in cmdline in second kernel (not uuid please)
and do some stress testings ? 

or enable the dynamic debug by append:
dyndbg='file kernel/power/hibernate.c +p;file kernel/power/snapshot.c +p'
Thanks

Yu

serial output from debug kernel - need advice

Aaron, I was able to build a debug kernel with usb-to-serial debugging enabled. I was able to get some output to the serial console by appending "debug ignore_loglevel no_console_suspend=1 console=tty console=ttyUSB0,115200n8" to the GRUB_CMDLINE_LINUX in grub. 

I was not able to get the system to successfully hibernate and resume even once in this configuration. It appears that the serial output really slows everything down. The output from that test run is attached here, even though it doesn't show the issue we're talking about.

You will have to tell me what options to enable to get the output you want on the serial console. Please advise. 

I will try Chen's patch next.

serial output from debug kernel - NO no_console_suspend parameter

This time I removed the no_console_suspend parameter from the boot commands and I was able to get it to hibernate and resume successfully a few times with the serial console working. After about 6 cycles I was able to reproduce the failure, but the serial log doesn't show anything.

log with call trace

I ran a bash script that repeated the built in test interface many times:
--------------
#!/bin/bash

for i in {1..100}
do
  	echo core > /sys/power/pm_test
        echo shutdown > /sys/power/disk
        echo disk > /sys/power/state
        sleep 5
done
--------------

After a few runs I stopped the script and checked my logs. A warning and a call trace came up. Does this mean anything? 

Full log is in the attachment.

hibernate error

This general protection fault was triggered on resume.
Comment 20 Hemant Kumar 2015-09-27 13:48:35 UTC
So I got similar GPF on resume. Again not always. But I think this may be unrelated to issue we reported earlier. The GPF was triggered at GDM login screen. While earlier hibernate/resume failures that I have seen results in blank screen and X does not even start (nor other services from what I can tell, I enabled SSH on laptop and see if I can SSH to it when it freezes).



Matt, did you update your BIOS to 1.17? Lenovo posted a new BIOS update. I have updated mine and saw above GPF (could be unrelated to BIOS update).

Hemant,

WOOHOOO Success!

I have applied Chen's patch to my kernel and have been able to hibernate/resume successfully 15+ times in a row. Before I would get 3-8 successes before a failure. I am confident that his patch did something.

Will you apply the patch and do some testing as well?

I will continue to test for the next few days.



----------
SIDE NOTE:
The debug kernel I built and testing using the kernel's built in test interface have gone nowhere, but I posted the info so Aaron and Chen can have some idea where the problem isn't located.
Comment 22 Matt Schepers 2015-09-27 22:38:28 UTC
In response to comment 15:

The bug has returned! However the probability of occurrence has gone way down. I have gotten 10-20 hibernate resume cycles each time before seeing the bug. Previously it was 3-8 cycles. 

Chen,

I think the patch helped, but did not completely fix the problem. You will have to instruct me on how to get further debug information.
Comment 23 Aaron Lu 2015-09-28 02:57:40 UTC
About serial log: it doesn't help much with USB converted serial, as that is actually a USB device sitting on top of a PCI device which means the log will only appear after the PCI and USB subsystem are initialized/resumed(the same is true for netconsole). In the case of a kernel problem, that usually doesn't happen. My previous comment about serial log means the real serial port, which is only available on develop/debug platform nowadays.

OK. How do we proceed? Do you need any additional test data from me?
Comment 25 Chen Yu 2015-09-28 03:50:52 UTC
Hi, Matt,
that patch is just to replace possible 'panic' during resume with a 'failure',
can you please also do the test I mentioned above:
(without my patch applied)

1. compile your disk driver as build-in (CONFIG_SATA_AHCI=y for example)
2. boot system with init=/bin/bash
3. after boot up,  do:
   3.1 swapon /dev/sda3 (your actual disk partition, not uuid please)
   3.2  echo disk > /sys/power/state,
4. push power button to boot up again,  append resume=/dev/sda3 in cmdline for second kernel (not uuid please), to see if it works.

These steps are to confirm if it related to driver problem or a critical kernel bug.
thanks!
Comment 26 Hannes Fuchs 2015-10-28 10:01:23 UTC
Hallo,

same Problem on ThinkPad S540 (LENOVO 20B3CTO1WW/20B3CTO1WW) with debian/testing. I'm using also disk encryption (LUKS with LVM) on a SSD (SAMSUNG MZ7TD256HAFV-000L9)

I also tried to get rid of systemd and used sysvinit with the same result, so I'm back using systemd.

Since Matt seems busy I tried these steps. I compiled the Kernel with CONFIG_SATA_AHCI=y booted into with init=/bin/bash:
 - swapon /dev/mapper/SSD--VG-swap
 - echo disk > /sys/power/state
 - Started up the maschine with resume=/dev/mapper/SSD--VG-swap
It worked and I was back on the cmd (bash)


For now i could set the resume parameter and some debugging kernel parameters (dyndbg='file kernel/power/hibernate.c +p;file kernel/power/snapshot.c +p') and log the memory usage before hibernation.
Comment 27 Chen Yu 2015-10-29 02:40:19 UTC
Hi, Hannes
does your thinkpad have the same problem with Matt's:
it failed to resume from hibernation with black screen? because according to
your test above, it appears to me that there is a driver problem, and I suspect it is related to graphics and sometime maybe due to insufficient memory when hibernating(hibernation needs 50% of the memory). So can you please help test again  with CONFIG_DRM_I915 not set and compile the kernel again? thanks!

Hi,

i assume it's the same problem. Sometimes hibernation works and sometimes it fails. If it fails, I can see the image loading (removed "quiet" from kernel parameters) until 100% and then I'm stuck on the "black" screen.

Yesterday I had some time and played around. Hibernation with a low memory footprint (free says about 200-400M from 16G RAM) works flawlessly but it seems if more memory (about 600M) is used it will fail to resume.

Today I tried the LTS Kernel 3.18.22 and this one works even with a memory usage of 5G or more.

So I guess it's something with in direction memory dumping to swap? My swap partition is bigger than my memory, not much but it worked it the past and also with 3.x kernel.

When I configure my laptop without CONFIG_DRM_I915 it will not boot. Or should I boot to bash, fill the memory and test again?

Do you mean, after the monitor shows that image is 100% loaded, a moment later, the system turns into black?

I'm not sure how the memory occupation would affect the resuming of hibernate, since you get 'black screen', I'd prefer to confirm if it is related to i915 graphic displaying problem first.

It's not really a black screen, it's stuck at 100%. See appended image as screenshot.

I ran multiple tests to be safe:
I.) Kernel 4.2.5 *without* CONFIG_DRM_I915, CONFIG_SATA_AHCI=m, into init=/bin/bash
II.) Kernel 4.2.5 *without* CONFIG_DRM_I915, CONFIG_SATA_AHCI=y, into init=/bin/bash
III.) Kernel 4.2.5 *with* CONFIG_DRM_I915, CONFIG_SATA_AHCI=m, normal boot into DE
                                                                                                                                     
I.)
I compiled the Kernel 4.2.5 *without* CONFIG_DRM_I915 and booted with the following boot params:
root=/dev/mapper/SSD--VG-root ro resume=/dev/mapper/SSD--VG-swap init=/bin/bash 
After booting I did this:                                                       
1. swapon /dev/mapper/SSD--VG-swap                                              
2. echo disk > /sys/power/state                                                 
3. power on with the mentioned boot params                                      
4. back to 2.
I resumed 15 times without a problem. The memory consumption was about 42M, what I checked with "free -m". So it seems hibernation works fine. I think I can do this the whole day long.

At this point I began to allocate memory with a simple python script. Therefore I started screen, allocated memory and began again with a loop of hibernate/resume cycles. After every 3 successful hibernate/resume cycles I increased the memory usage.
a. +32M → ~88M memory consumption → 3  hibernate/resume cycles → no problem
b. +64M → ~121M memory consumption → 3  hibernate/resume cycles → no problem
c. +128M → ~186M memory consumption → 3  hibernate/resume cycles → no problem
d. +256M → ~314M memory consumption → 3  hibernate/resume cycles → no problem
e. +512M → ~571M memory consumption → 3  hibernate/resume cycles → no problem
f. +1024M → ~1086M memory consumption → 3  hibernate/resume cycles → no problem
g. +2048M → ~2117M memory consumption → 1st resume → failed

II.)
Same as in I.) +2048M → ~2116M memory consumption → 1st resume → failed
I booted again into bash and wanted to force the error:
a. +4096M → 4174M memory consumption → 3  hibernate/resume cycles → no problem
b. +8192M → 8295M memory consumption → 1st resume → failed



III.)
After booting into /bin/bash and the hibernate/resume cycles I booted my old Kernel 3.18.22 and recompiled the Kernel 4.2.5 *with* CONFIG_DRM_I915 *enabled*. In this case the boot params were set to: 
root=/dev/mapper/SSD--VG-root ro resume=/dev/mapper/SSD--VG-swap                
So I logged into my DE (which is i3) and did following:                         
1. systemctl hibernate                                                          
2. power on, was back to my desktop                                             
3. systemctl hibernate                                                          
4. power on ... and so on                                                       
Also here I resumed 15 times without a problem, the memory consumption was about 225M. So, also no problem with resume. Then I increased the memory usage with a python script:
a. +32M → ~265M memory consumption → 3 hibernate/resume cycles → no problem  
b. +64M → ~300M memory consumption → 3 hibernate/resume cycles → no problem  
c. +128M → ~365M memory consumption → 3 hibernate/resume cycles → no problem 
d. +256M → ~392M memory consumption → 2nd resume → failed!

Conclusion:
The behaviour is very strange. It seems that I can force a failure if I allocate more memory, but I can not say which is the limit.

I tested the RAM modules with memtest, no error.

Script to allocate memory:
#!/usr/bin/env python
import sys
import numpy
if __name__ == "__main__":
    if len(sys.argv) == 2:
        try:
            m = int(sys.argv[1])
            print "allocating %i Mbytes" % m
            tmp = [numpy.random.bytes(1024*1024) for x in xrange(m)]
            print "%i Mbytes allocated" % m
            raw_input("press key to exit")
        except:
            print "can not parse arg: <%s>" % sys.argv[1]
            sys.exit(1)
    else:
        print "one arg needed"
        sys.exit(1)
    sys.exit(0)

Comment 34 Hannes Fuchs 2016-01-31 14:35:23 UTC
Same here on my Lenovo S540 (Intel i5-4200U). The behavior is the same; stuck on 100% loading the image. With Kernel 4.4 the maschine reboots after some seconds stuck on 100% image loading.

Like previously it fails somtimes but not every time and it seems to be it can be "forced" by high memory usage.

disable BUG_ON when resuming in IRQ rcu grace period

I found another bug might cause the system hang/reboot after restoring the system, not sure if it is related to this bug, but it would be nice if you guys can help test if this patch works(do not apply any other patches). plz have a try. otherwise I might need to propose some debugging patches to track your problems. thanks.
Comment 36 Matthew Horan 2016-01-31 17:35:27 UTC
Still hanging with the latest patch applied.

I see the same behavior as Hannes, where at low memory utilization on hibernate (~1GB), resume works fine. Once I get up around 2GB, resume hangs. My system has 16 GB RAM (and 16 GB swap).
Comment 37 Hannes Fuchs 2016-01-31 19:31:27 UTC
Thanks for your effot Chen. 

I also applied your latest patch on Kernel 4.3.3 and 4.4 and can confirm the behavior described by Matthew. With a memory usage above 1GB the resume will fail, but mostly not on the first attempt.
Comment 38 Tom Honermann 2016-02-20 03:49:10 UTC
I've been experiencing this problem on a Lenovo T450s running Kubuntu 15.04, Linux 4.2.0-27-generic.  Has anyone had any luck identifying a fix or workaround for this?  For me, resume fails at least 75% of the time with the same symptoms reported; resume starts, shows loading of the image, screen goes black, fan kicks on, unable to login remotely, fn keys work, but otherwise system seems unresponsive to the keyboard.

I'll be happy to provide any logs or other information that would be useful to diagnose.
Comment 39 Hannes Fuchs 2016-02-20 13:08:01 UTC
Hello Tom,

the only workarounds are:
- avoid hibernate and use suspend on new kernel versions (4.x)
- use an older kernel, ex. longterm 3.18.x (works for me)
Comment 40 Daan van Rossum 2016-04-07 13:31:09 UTC
I am having the same issue (black screen after resume, with a likelyhood that seems to increase with memory usage) on a T450s with linux-4.4.5.

One useful workaround that I would like to share is to use Intel Rapid Start Technology instead.  A suspended machine is automatically hibernated after a set amount of time.  This mechanism doesn't use the kernel's hibernate/resume mechanism and works flawlessly.  The only change required is to designate the swap partition as type IRST instead of swap.
Comment 41 Tatsuyuki Ishi 2016-04-27 09:25:46 UTC
Reproduced.
Hardware is ThinkPad X1 Yoga, kernel is 4.6-rc5.

I think this is widely applying to ThinkPads. Changing the title may be appropriate.
Comment 42 Rafał Przywara 2016-05-13 10:36:14 UTC
I have the same issue on Arch with kernel 4.5.3-1-ARCH. The first resume after boot is usually OK, later ones fail. It is somehow related to memory usage. I have written a small .c app to allocate almost all RAM to easily reproduce it without destop environment (XFCE). Since failed resume doesn't get written to the logs I have attached the screenshot. It fails with "general protection fault: 0000 [#1] PREEMPT SMP". My laptop is Lenovo G710.

Thank, this is useful, could you also share your cpp and your kernel config? 
besides please help check this 'patch' if there is any warning(reproduce) during resume?

I patched kernel 4.5.4 but I don't see any warnings in logs pertaining to it. Meanwhile I testes various kernels and so far the latest working for me is 3.19.3. Next one I tested ie 4.0.7 hangs during resume. How I test it:

1) reboot
2) run swap.c to allocate some memory
3) in another tty do systemctl hibernate
4) resume
5) if it doesn't hang then goto 3)
 
Usually second cycle hangs. Attached: kernel 4.5.4 config and source of my alloc test app.

Comment 48 Daan van Rossum 2016-05-20 14:15:22 UTC
After a successful resume from hibernate the following error message is printed:
 [drm:gen9_set_dc_state [i915]] *ERROR* DC state mismatch (0x0 -> 0x2)

Is it useful to try to always force the corrective action for this mismatch to see if that fixes the black screen issue?  If that were the case perhaps the mismatch detection is not robust.  Although, why the mismatch happens in the first place is perhaps a more useful question.

P.S. I also tried Chen Yu's patch (7454481) but I don't get the patched-in warnings printed during resume either.
Comment 49 Daan van Rossum 2016-05-20 14:44:13 UTC
I also see this warning appear in the logs, not sure if relevant:

Comment 50 Dylan Durdle 2016-06-04 15:54:36 UTC
Just dropping in to report I have the same issue.  Been living with it on a Carbon X1 2nd generation for months (a year?).  Been trying all kinds of reworking of settings (BIOS and power management).  Got a Carbon 4th generation this week -- same issue.

The odd thing is when I use 3.16.0.7 kernel, I had same issue.  Only when I used really older kernels did I not have the issue.  But the 2nd generation Carbon X1 had that annoying capacity touch keyboard, so you need to use 3.14 or later if you want to properly use the machine.  If you can live without a functioning keyboard, 3.9 I was using prior had no issue.

I use BTRFS and overlays so I prefer to stay more current.

The suggestion around IRST is mute.  I did enable this and start using it.  Was working ok, but I noticed that if you left the machine sit for a few days and try to start it up, it seemingly had forgotten it was in "deep sleep" and instead of awakening from "deep sleep" via IRST, it was cold booting.  Also witnessed an annoying bug when the system would start up randomly from deep sleep and not shutdown until it hit 47%.  I would know it had woken up because I would start up the machine and it would be cold booting and battery would be 47% (having been either 80% or fully charged the night before).  I had my setting set at 30 mins, so it would be suspended for 30 mins, then wake up and go into deep sleep.  At this point suspend light goes off, and next time you open the lid, you see "returning from deep sleep".  To test this "waking up" theory after in deep sleep, I left it plugged in AC last week and put it in IRST (suspend, then confirm 30 mins later in deep sleep, went to work, and 8 hours later, got home to a system that was booted up and sitting at grub.

I would rather use hibernation.  It works on all kernels I throw at it on all my other machines (thinkpad and other).  Would go months before cold boots on a T420.

Is there any difference with the following patch applied?(don't apply #Comment 44):
https://patchwork.kernel.org/patch/9158227/
Comment 52 Daan van Rossum 2016-06-07 08:50:43 UTC
I applied 9158227 to linux 4.6.1 but still get the black screen at resume from hibernate.  Are there any helpful messages in the logs that we should look for?

By the way, the chance that a resume fails seems to be higher in the 4.6 kernel than in 4.5.  But I have not tested this often enough to be able to say how much it differs.
Comment 53 Hannes Fuchs 2016-06-15 10:02:50 UTC
After two days of Kernel compiling and many hibernations/reboots I have some results that might help.

tl;dr:                                                                          
The latest working Kernel (for me) is 3.18.22, on 3.18.23 the resume did not work and hangs on 100% while loading the image. The patch (9158227) mentioned in #Comment 51 did not work. I found one odd behavior: When the memory usage increases after a successful resume, the next resume from hibernation will fail, if it keeps the same it works (kernel version doesn't matter), until ~6GB. 6 GB (16 GB physical memory) will mostly fail.


How I tested:                                                                   
1.) Boot into Kernel x.y.z                                                      
2.) Allocate 1GB with Rafał Przywara alloc_app                                  
3.) systemctl hibernate                                                         
4.) resume                                                                      
5a.) If it doesn't hang goto 2.) but close app and reallocate.                  
5b.) After 3 successful resumes increase the allocation: 2GB, 4GB, 6GB, 8GB, 14GB and resume until it hangs
5c.) If it hangs, try again (mostly it will work with the new memory allocation), after 3 hangs abort


At first I wanted to know which kernel is the latest working one and at which version the error occurs, so I tested the 3.18.x versions, but here I made a "fast" test, which means I began with 8GB allocation and if it works I increased it to 14 GB (which will fail, except 3.18.22 and lower)
* 3.18.35 - failed at 8 GB
* 3.18.24 - failed at 8 GB
* 3.18.23 - failed at 8 GB
* 3.18.22 - working

Than I made more runs with 3.18.22:
+--------+---------+---------+--------+
| *Size* | *Run 1* | *Run 2* | Run 3* |
+--------+---------+---------+--------+
| 1 GB   | OK      | OK      | OK     |
| 2 GB   | OK      | OK      | OK     |
| 4 GB   | OK      | OK      | OK     |
| 6 GB   | OK      | OK      | OK     |
| 8 GB   | OK      | OK      | OK     |
| 14 GB  | OK      | OK      | OK     |
+--------+---------+---------+--------+
Looks good and works.

For 3.18.23:
+--------+---------+---------+--------+---------+---------+
| *Size* | *Run 1* | *Run 2* | Run 3* | *Run 4* | *Run 5* |
+--------+---------+---------+--------+---------+---------+
| 1 GB   | OK      | OK      | OK     | skipped | skipped |
| 2 GB   | FAILED  | OK      | OK     | OK      | skipped |
| 4 GB   | FAILED  | OK      | OK     | OK      | skipped |
| 6 GB   | FAILED  | OK      | FAILED | FAILED  | FAILED  |
| 8 GB   | FAILED  | OK      | FAILED | FAILED  | FAILED  |
| 14 GB  | FAILED  | FAILED  | FAILED | skipped | skipped |
+--------+---------+---------+--------+---------+---------+
When the memory allocation was increased, the resume failed. But after a fresh boot it worked with the same allocation (2GB/4GB Run2 - Run4). Run2 with 6 and 8 GB was only luck.


After that I tested the 4.x kernel versions. All failed at 8 GB, so I didn't take a deeper look into it.


Then I tested the patch (9158227) with different kernels:
* 3.18.23 - failed at 8 GB
* 3.18.35 - failed at 14 GB
* 4.1.26  - failed at 14 GB (3rd run)
* 4.4.13  - failed at 8 GB
* 4.5.7   - failed at 8 GB
* 4.6.2   - failed at 8 GB

Kernel 4.1.26 (patched) looked promising, so I made more tests:
+--------+---------+---------+--------+---------+---------+---------+
| *Size* | *Run 1* | *Run 2* | Run 3* | *Run 4* | *Run 5* | *Run 6* |
+--------+---------+---------+--------+---------+---------+---------+
| 1 GB   | OK      | OK      | OK     | skipped | skipped | skipped |
| 2 GB   | FAILED  | OK      | OK     | OK      | skipped | skipped |
| 4 GB   | FAILED  | OK      | OK     | OK      | skipped | skipped |
| 6 GB   | FAILED  | FAILED  | OK     | FAILED  | FAILED  | FAILED  |
+--------+---------+---------+--------+---------+---------+---------+
The 8 and 14 GB test were skipped.


Hope this helps.

This patch (9172981) fixed the bug for me. Tested with kernel 4.7.0-rc3 and applied patch (9172981).

Allocated memory: 1x 8 GB, 5x 14 GB.

Great work!
Comment 56 Hemant Kumar 2016-06-16 03:59:07 UTC
our of curiosity - can this be backported to LTS kernel 4.4 - which is what a lot of distros are shipping right now?
Comment 57 Matthew Horan 2016-06-16 12:19:39 UTC
The above patch alone did not resolve this issue for me when applied to Debian's 4.5 kernel. So, there are either other patches that need to be packported, or this issue is not actually resolved. 

I also encountered issues getting my system to enter hibernation after applying this patch. My system would often lock up completely. 

I'll try a more recent kernel tonight and report back.
Comment 58 Daan van Rossum 2016-06-17 08:07:10 UTC
This patch seems to completely fix the issue for me, on linux-4.6.2.

Thanks a lot for this fix!
Comment 59 Matthew Horan 2016-06-17 11:58:06 UTC
All is well with kernel 4.7.0-rc3, so there may be something else required to get this working in 4.5 (and possibly earlier kernels.)

Thanks for the fix!
Comment 60 Dylan Durdle 2016-06-17 15:43:06 UTC
Installed kernel 4.6.2, and then downloaded the source, patched, and then installed the patched kernel.  It survived the hibernation thaw but system is unstable.  Within a few mins I was not able to invoke any applications or even reboot the system.  

will continue to test.
Comment 61 Dylan Durdle 2016-06-17 16:02:55 UTC
The freeze mins following thaw from hibernation had the following event message associated with it:

perf: interrupt took too long (2507 > 2500), lowering kernel.perf_event_max_sample_rate to 79750

It might be some other issue but could be related to this change.  Will continue to test.
Comment 62 Dylan Durdle 2016-06-24 13:14:09 UTC
I have been testing over the past week.  No more unstableness after thaw, but this morning I was greeted with the blinking cursor on blackscreen when trying to thaw.

I noticed just prior to and continuing on since, a TPM error on bootup (TPM could not read pcr).
Comment 63 Chen Yu 2016-07-01 05:01:44 UTC
Guys, 
latest patch at:
https://patchwork.kernel.org/patch/9208541/
https://patchwork.kernel.org/patch/9202321/
Would you please help check if it works?
Comment 64 Daan van Rossum 2016-07-01 06:49:55 UTC
Chen, thanks for passing this on.  I have two questions:

Patch 9172981 already fixed the issue for me.  It seems that patch 9208541 is a newer variant, but how do we determine whether it is better than the old patch?  What are the issues with the old patch that are solved in the newer version?

And how is patch 9202321 to be tested?  How does it relate to the black screen on resume issue?
Comment 65 Chen Yu 2016-07-01 07:34:36 UTC
The old patch does not solve a corner case that the restore_code may be in huge page, and we did not setup mapping for it. The patches are almost the same.

9202321 is just to avoid theoretical nonboot cpu panic during resume. No special actions are required to test this patch.
Comment 66 Christoph Hartlmueller 2016-07-01 18:00:32 UTC
Hi there, I just applied both patches (9208541 + 9202321) to Manjaro's current 4.6 Kernel (4.6.3-1-MANJARO) and it fixed the hibernate issue for me on a Thinkpad Yoga S1. Everything runs nicely so far and I could do a couple of hibernates with about 90% of 8GB RAM used.
I will report back if I run into any issues.

Thanks a lot for the fix!!

Comment 67 Daan van Rossum 2016-07-05 06:29:43 UTC
I can report that the two patches (9208541 + 9202321) work well on a T460s, too.  I have tested hibernate-resume extensively and not experienced any black screen (or halts of any sort) on resume.  I consider this bug fixed.

Thanks a lot to Chen Yu and Rafael Wysocki for fixing the issues!!

Patch 9208541 and 9202321 work perfectly on my laptop thinkpad T550.  
But not ok with my PC, ThinkCentre M8500. It got panic every time after resume from hibernation. The more times it hibernate the panic worse and finally crash completely. 
So I applied patch https://bugzilla.kernel.org/attachment.cgi?id=188341 too. Then panic was solved, but my linux crash in various ways. Sometimes page fault, sometimes stuck on opening terminal. And certainly it will freeze completely if I press ctrl+alt+f1 at this moment. I think it's still a panic, but I get nothing with dmesg.

Please help. @Chen Yu.

Please check with latest upstream Vanilla kernel without any other patches applied(most of them have been merged upstream) and please provide the panic log if possible.

chromium damage hibernation

If I open chromium especially when I open tons of tags, my system will very slower and finally got totally panic and freeze. Before system freeze, there will be many syslog sometimes, like this: 
kernel: page: count: mapcount mapping: (null) .

I have removed all number inside that message.


I compile kernel 4.6.4 from source and apply patch 9208541 and 9202321.

cause I need the unity mode of vmware 11 which disabled on vmware 12. And it's difficult to make vmware 11 be compatible with newer kernel. So I keep using kernel 4.6.4.

Please help~
