Cannot hibernate

English Install/Boot/Login
#1

Hibernation with this computer used to work with opensuse 12.3. With 13.1, resuming after hibernation is actually a reboot.

RAM is 16 GiB and swap is 17 GiB. Swap (partition 1) is unused, but active:



# free -m
             total       used       free     shared    buffers     cached
Mem:         16001       2112      13888          0         96        876
-/+ buffers/cache:       1140      14861
Swap:        17404          0      17404



#  swapon -s
Filename                                Type            Size               Used    Priority
/dev/sda1                               partition       17822716        0       -1

The relevant lines from menu.lst:

title Desktop -- openSUSE - 3.11.6-4
    root (hd0,1)
    kernel /boot/vmlinuz-3.11.6-4-desktop root=/dev/disk/by-id/ata-...-part2 resume=/dev/disk/by-id/ata-...-part1 splash=verbose showopts
    initrd /boot/initrd-3.11.6-4-desktop

There are a few suspicious lines in log file pm-suspend.log which I don’t understand; other lines report success:

usr/lib/pm-utils/sleep.d/00powersave hibernate hibernate: success.
Running hook /usr/lib/pm-utils/sleep.d/02rtcwake hibernate hibernate:
rtcwake alarm not enabled in /etc/pm/config.d/rtcwake.config, doing nothing...

/usr/lib/pm-utils/sleep.d/02rtcwake hibernate hibernate: success.
Running hook /usr/lib/pm-utils/sleep.d/06autofs hibernate hibernate:
autofs.service - Automounts filesystems on demand
   Loaded: loaded (/usr/lib/systemd/system/autofs.service; disabled)
   Active: inactive (dead)

Visually, it looks like hibernation is successful, but at waking up, the swap partition is ignored.

How shall I proceed to debug?

So you are using Grub not Grub2?

Can’t say I have tried it recently, I pretty much only use Suspend

#3

I use Grub.

Sleep (suspend to RAM) also works marginally, sometimes not restarting correctly. Used to work with opensuse 12.3. Otherwise, the computer works correctly.

Hibernation by

/usr/sbin/pm-hibernate

from command line fails the same way as from KDE’s logout menu.

Oh.
I asked because there is a bug on the 32 bit kernel in 13.1 that impedes
hibernation.
