AFAIK There are 3 versions of hibernation code. Two that are part of the
official kernel and one that need a patch (suspend2). This latter is
more advanced and should perform better but is being actively developed
and changes frequently. The two versions included in the official 2.6.x
kernel are Pavel's swsusp and Patrick Mochel's PM suspend. You have to
check which one is compiled in your kernel. Each one has it's own
starting command.
So I just did that:
echo shutdown > /sys/power/disk; echo disk > /sys/power/state
It stops, i.e suspends the system. Very quick. Pop goes the speaker
and power goes off. Leaves the external modem connected.
Then what. I have no option but hitting the power on button and
selected the lilo image where I had added "resume/dev/hda13", my
swap device.
AFAIK, we have to wait for improvements on the ACPI side in order to
have a wake-on-lid kind of resume.
That's where things went wrong: it just booted and of course found
bad disks etc. rebooted itself and I had to clean things up.
Did you reinstalled lilo after changing it?? Is your "resume=/dev/..."
well written? It should work. There is however the possibility that your
harddrive cache was not written to the disk Some drives have this kind
of problem.. You can use hdparm to disable the cache before the suspend
command and reenable if after.
Of course ;-) I ran lilo after the resume addition.
It would seem that the resume=/dev/ is all that is needed for boot parm?
I added it to the ones I already had.
I will try disabling cache to the hda drive where the swap is.
