Hi all,

I cannot hibernate my laptop, running pm-hibernate seems to hibernate correctly (HDD light flashing, screen off), but then it switches right back on without me touching anything. pm-suspend works fine, it suspends to RAM correctly. I am using gentoo-sources kernel with pm-utils (and KDE). I've found the following suspicious lines in /var/log/pm-suspend.log

Code:

/usr/lib64/pm-utils/sleep.d/99video hibernate hibernate: success.
Mon Nov 19 17:18:38 GMT 2012: performing hibernate
/usr/lib64/pm-utils/pm-functions: line 316: echo: write error: No such device
Mon Nov 19 17:18:59 GMT 2012: Awake.
Mon Nov 19 17:18:59 GMT 2012: Running hooks for thaw
Running hook /usr/lib64/pm-utils/sleep.d/99video thaw hibernate:


I've checked in pm-functions, and this line is
Code:
echo -n "disk" > /sys/power/state

/sys/power/state does exist, and it contains "mem disk".

Does anybody have any idea how to fix this?

Kai

Does your system fail to save state to disk or does it fail to halt after the state is saved? If the former, then hibernation does not work at all. If the latter, then the machine is rebooting and resuming when it should have halted. Based on the error log you provided, it looks like the system does not save state to disk. Based on your description, it sounds like the machine reboots and resumes.

What is the output of emerge --info? Are you sure you included in the kernel the required functionality for hibernation?

Sorry for being light on the details, that is about all I can figure out. What are the necessary config files I should be watching? My kernel .config is here http://pastebin.com/cWVc6cRR, and I think I've set all the necessary options found in various linux hibernation guides. I *think* it is writing to disk, since I get a lot of hard disk activity before and after, but I am not sure what else I could check.

Below is emerge --info:

Does the kernel print anything to dmesg when you attempt to hibernate?

No, there is nothing on dmesg after hibernate. There is nothing after a sleep either, but that works correctly. Again, pastebin to a dmesg from a restart, followed by hibernate, followed by sleep here: http://pastebin.com/h3uEjiED

What is the output of free -m? Have you checked whether a bare hibernate works correctly?

free -m:

Code:

             total       used       free     shared    buffers     cached
Mem:          3955       2299       1656          0        263        936
-/+ buffers/cache:       1099       2856
Swap:         4095          0       4095


What do you mean by 'bare hibernate'? I'll try it as soon as I know :)

EDIT: I read a post that says swap must be 2*ram size, rather than just larger than ram size. I've done that, but still no luck. Free now says:

Code:

kai-laptop ~ # free -m
             total       used       free     shared    buffers     cached
Mem:          3955        716       3239          0          4        136
-/+ buffers/cache:        575       3379
Swap:         8191        956       7235

What happens if you make a simple
Code:
echo disk > /sys/power/state
as root ?Maybe before that you mshould make a
Code:
echo 0 > /sys/power/image_size
as root.

Right, here's what happened:

Code:

kai-laptop ~ # cat /sys/power/image_size
1657577472
kai-laptop ~ # cat /sys/power/state
mem disk
kai-laptop ~ # echo disk > /sys/power/state
echo: write error: no such device


At this point the system does the usual 'hibernate' - screen turns off, HDD light flashes for a while, CD drive makes some noise (it is empty) and then I'm back to my desktop (not locked, I'm assuming that's normally a KDE thing).

Code:

kai-laptop ~ # echo 0 > /sys/power/image_size
kai-laptop ~ # echo disk > /sys/power/state
echo: write error: no such device


This does the same, but the whole process takes somewhat longer (i.e. screen turns off, but takes longer to come back on, and then the desktop is frozen for a bit while the HDD light is on).

Any ideas? Thanks for the help so far!

Kai

And your kernel is configured for hibernation ?
Code:
tfoerste@n22 ~ $ zgrep CONFIG_PM_STD_PARTITION /proc/config.gz
CONFIG_PM_STD_PARTITION="/dev/sdb2"
and the swap partition (which is used for that) isn't encrypted ?

My .config is posted earlier somewhere, here's the relevant line:

Code:

kai@kai-laptop ~ % grep CONFIG_PM_STD_PARTITION /usr/src/linux/.config
CONFIG_PM_STD_PARTITION=""


I have a swap file rather than a swap partition, what should I set here for this?

I do not have a separate swap partition. I have a swap file that is at /swapfile

Here is my /etc/fstab:
Code:

/dev/sda2               /boot           ext2            noauto,noatime  1 2
/dev/sda6               /               ext4            noatime         0 1
/swapfile               none            swap            sw,loop         0 0
/dev/cdrom              /mnt/cdrom      auto            noauto,ro       0 0

AFAIK you need a separate partition of type "Linux swap" to use s2disk.

Ah, I didn't realize that. Any chance the fancy tuxonice things will be merged into gentoo-sources? That'd be nice :)

Meanwhile, hibernate is now working, thanks (minus some residual KDE weirdness on resume). Sorry to cause so much trouble with that, I didn't realize it wasn't supported.

I doubt it will ever be merged into the kernel. Lots of politics. :evil:
