Hibernate isn't working properly (pm-utils)

Niamh · 2011-10-03 11:08:37

After installing pm-utils, suspend worked out-of-the-box, however hibernate doesn't work properly.
Laptop shut's down (goes to hibernate) and after turning it back on, it doesn't load the previous state.
(I've testet it couple of times by leaving random apps opened - libreoffice writer, chromium etc.)
It's as if I'm shutting it down rather then hibernating.

I did all the basic setup like adding "resume=/path/to/swap"
and afterwards added the "resume" hook to mkinitcpio, and it still doesn't work.
I've also tried hibernate in test mode as it's suggested here (found the link on wiki pages) and according to the test, it should all be working.

My guess is that image saved to swap isn't restored after returning from hibernation for some reason, so if anyone has any ideas... I'd really appreciate it

Check /var/log/pm-suspend.log for clues, and watch for relevant messages at boot time, when the resume hook is activated.

Niamh · 2011-10-03 12:54:49

According to pm-suspend.log hibernation is successful, and I haven't seen anything different during boot time. I'm not
sure if there should be anything different during boot time, but it looks just the same as if I didn't have the resume hook.

Is there any way to debug or make a bit more detailed test only with resume part? That seems to be problem, although I
can't figure out why.

Check the kernel log for something like this:

PM: Hibernation image not present or could not be loaded

Did you rebuild the initrd image after making the changes to mkinitcpio?

Niamh · 2011-10-03 13:23:21

Yes, just as it's described in wiki.

the sad clown · 2011-10-03 13:28:01

Does the kernel log indicate anything?

Niamh · 2011-10-03 14:38:24

PM: Checking hibernation image partition /dev/sda3
input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input0
PM: Hibernation image not present or could not be loaded.

Definitely a problem. Although, this are the only indications of swap being created.

Some googling showed that there shoud be some steps including syncing filesystems and actually logging the
creation of image, but there are none (there's enough swap memory to create one).

Well, the "image not present" shows that something went wrong with your resume hook. Do you mind posting the hooks array from mkinitcpio.conf? Maybe the grub menu.lst for good measure as well.

Niamh · 2011-10-04 00:19:31

menu.lst

Except "resume", everything else is default setting.

Is your swap large enough? What does free say about your swap?

Niamh · 2011-10-04 01:21:33

It's large enough and /dev/sda3 is the swap partition.

What is the output for this:

cat /sys/power/state

Also, have you tried hibernating with just acpi instead of using pm-hibernate?

echo disk > /sys/power/state

Output of "cat /sys/power/state"

 standby mem disk

I've tried that as well, but the result is still the same. There are no changes in kernel.log compared to pm-hibernate.

the sad clown · 2011-10-05 00:33:10

Then it isn't pm-utils (which is the front end), it's with acpi. I don't think I can help you. The only thing I can think of is that despite the fact that suspend to ram works for you, that a module is hanging and interfering with hibernate. I don't even know if that is possible, but it is the only thing that comes to mind. Sorry I couldn't get hibernate working for you.

Niamh · 2011-10-05 01:08:50

Thank you for your time. I'll keep the thread open if someone else gets any ideas

chmurli · 2012-01-21 10:18:40

Hi, I had similar problem.
Do you use swapfile or normall swap partition? If swapfile you have to add resume_offset to starting parameters and resume must point swap partition not swap file explicitly!
I had make changes to: https://wiki.archlinux.org/index.php/Sw … e_resuming

baronleonardo · 2015-05-14 06:17:40

I have the same problem here

baronleonardo, please don't necrobump.
