Hi,
I am struggling to make hibernation work on my ASUS laptop
(Unfortunately I do not know the exact model number, it was from the L
series, I reckon).
I've decided to use the suspend-to-disk method and use the swap
partition (/dev/hda3) for this end. I use stock kernel version 2.6.22.
The 'free' command shows the following:
(...)
Swap: 949 0 949
So apparently the swap partition is ok.
I've configured hibernate for the above described idea and launched
'sudo hibernate -v3'
I see this on the console:
hibernate: Trying method in suspend2.conf...
hibernate: Trying method in disk.conf...
hibernate: Trying method in ususpend-disk.conf...
hibernate: Including configuration from common.conf
Then several more lines that basically indicate that everything works as
expected, the swap is big enough to hold the image (Image size: 366340).
My laptop powers off. Things go wrong when I switch it on, expecting to
resume my hibernate session.
What it does instead is that it boots like hibernation had never
happened at all without indicating what's wrong.
I copy a few lines of dmesg here that might be related to that problem:
Linux version 2.6.22-1-686 (Debian 2.6.22-3)
Kernel command line: root=/dev/hda1 ro resume=/dev/hda3
(...)
checking if image is initramfs... it is
Freeing initrd memory: 1292k freed
(...)
Unable to find swap-space signature
It also says sometimes:
swapon: /dev/hda3: Invalid argument. failed,
but this line is mysteriously missing from dmesg, I could see it quickly
scroll away but could never review it later (using dmesg or syslog)
When this happens, I do:
sudo mkswap /dev/hda3;
sudo swapon -a
so swap is restored and then try hibernating again, but that does not
help either.
In the hibernate.log, I could not spot anything wrong either:
Starting suspend at Sun Aug 26 18:57:19 CEST 2007
hibernate: [01] Executing CheckLastResume ...
Resumed at Sun Aug 26 18:57:19 CEST 2007
(...)
Starting suspend at Sun Aug 26 18:58:19 CEST 2007
(...)
Unloading blacklisted modules listed /etc/hibernate/blacklisted-modules
(...)
hibernate: [99] Executing DoUSuspend ...
hibernate: Running /usr/sbin/s2disk ...
I tried to nudge things by manually editing the grub menu.lst and adding
the resume kernel boot parameter:
kernel /boot/vmlinuz-2.6.22-1-686 root=/dev/hda1 ro
resume=/dev/hda3
And also by adding one line in /etc/hibernate/suspend2.conf to define
the SuspendDevice manually:
SuspendDevice swap:/dev/hda3
, but that did not help either.
I use acpi, also checked the BIOS parameters and browsed through several
forums but could not find an answer to this problem. I have an ATI
Radeon card that I've read on several occasions could cause problems but
I am not yet there to have this kind of annoyances, I think :)
Did any of you had serious experiences or any luck making this work on
an ASUS laptop? (As a secondary question, I would be happy to know why
certain lines that I see on the console when my laptop boots are
inaccessible later? Neither by dmesg, nor in syslog, see the example of
'swapon: /dev/hda3: Invalid argument. failed' above.)
Any help is much appreciated, thank you,
Balint
