Hello all,

On my netbook here, I did a fresh install of --current.

I cannot get hibernate to work, it seems to fall back to suspend.

In /var/log/pm-powersave.log I get this message:

/usr/lib/pm-utils/power.d/sched-powersave false: success.
Running hook /usr/lib/pm-utils/power.d/wireless false:
Turning powersave for wlan0 off...Error for wireless request "Set Power Management" (8B2C) :
SET failed on device wlan0 ; Operation not supported.
Failed

The netbook then seems to fallback to suspend at that point.

Thanks in advance.

Have you a resume partition (use swap) set? Is it big enough?

Post the o/p of
cat /sys/power/state

Hello,

from the free command:

Mem: 1014400 646044 368356 0 43772 325752
-/+ buffers/cache: 276520 737880
Swap: 1076316 0 1076316

my fstab:
/dev/sda6 swap swap defaults 0 0

from lilo.conf:
image = /boot/vmlinuz-generic-smp-2.6.37.3-smp
root = /dev/sda5
label = Linux
read-only
initrd = /boot/initrd.gz-2.6.37.3-smp

from my mkinitrd.conf:
# mkinitrd.conf.sample
# See "man mkinitrd.conf" for details on the syntax of this file
#
SOURCE_TREE="/boot/initrd-tree"
#CLEAR_TREE="0"
OUTPUT_IMAGE="/boot/initrd.gz"
#KERNEL_VERSION="$(uname -r)"
#KEYMAP="us"
MODULE_LIST="ext4"
#LUKSDEV="/dev/sda2"
#LUKSKEY="LABEL=TRAVELSTICK:/keys/alienbob.luks"
ROOTDEV="/dev/sda5"
#OOTFS="ext4"
RESUMEDEV="/dev/sda6"
#RAID="0"
#LVM="0"
#UDEV="1"
#MODCONF="0"
#WAIT="1"

So unless I'm missing something, I think I have all my bases covered here.

I even went so far as to issue hibernate as root, and the pc simply goes into standby.

It's easier to go from scratch:

You need resume=/dev/sdax as a kernel boot parameter, that drive defined in fstab as swap, if you're compiling a kernel put resume device in there.

The o/p of cat /sys/power/state should include the work disk. Hibernate manually with

sync; echo -n disk > /sys/power/state

Does it work, or what error does it throw?

Sorry my mistake, I did indeed have the resume= line in my lilo.conf up at the global append line.

I moved it down to the specific kernel as you suggested, reran lilo and still no luck.

What is interesting is:

when pm-hibernate is called, both /var/log/pm-powersave.log and /var/log/pm-suspend.log are updated to the time that I issued the hibernate command. Perhaps because hibernate is called, then fails, then it falls back to suspend; I'm not sure.

There is one line in the hibernate log that seems worth mentioning:

"/usr/lib/pm-utils/pm-functions: line 316: echo: write error: No such device"

And in the suspend log, there are these lines that are worth mentioning as well:

/usr/lib/pm-utils/power.d/sched-powersave false: success.
Running hook /usr/lib/pm-utils/power.d/wireless false:
Turning powersave for wlan0 off...Error for wireless request "Set Power Management" (8B2C) :
SET failed on device wlan0 ; Operation not supported.
Failed.

Seeing the wlan0 error there I just issued the hibernate again, and indeed the wifi is not turned off at all.

My netbook uses ath5k and I'm using wicd. I think I'm going to try blacklisting wifi as a test and see if anything changes. Will report back.

business_kid thanks again for all your help. It turns out I had the wrong partition number for swap in my lilo.conf. I cannot believe I didn't catch that, but none the less it works now. Thank again.
