Hello all,
First, I'm responding based on the page on opensuse
(http://en.opensuse.org/S2ram). And I'm responding because under
suse10.1, my laptop went to sleep and woke up just fine, but under suse
10.2, it no longer does (which is why it seems like a bug, as opposed to
a machine that's simply not supported). I should point out that I am
loading a repaired DSDT table at boot, and that I was doing so under
10.1 as well.
The output of s2ram -i :
This machine can be identified by:
sys_vendor = "Intel Corporation"
sys_product = "Calistoga & ICH7M Chipset"
sys_version = "Not Applicable"
bios_version = "Q3B21 "
This is a core duo 2.0G machine, built by Quanta, distributed through a
reseller program sponsored by Intel. I attached the output of lsmod at
the end of the message, in the event that's helpful.
As I understand it, suse 10.1 uses the powersaved, and 10.2 uses
pm-utils, but they both rely on s2ram. I'm a little unclear on that,
obviously if s2ram is completely new to suse 10.2, that's a different
story than "used to work and now doesn't."
Under suse 10.1, I simply set
/etc/powersave/sleep:SUSPEND2RAM_FORCE="yes", and made sure the lid
button event caused suspend to ram, and it worked flawlessly.
Under suse 10.2, when I try s2ram -f, the machine does sleep, and it
does wake up (in X mode), but it's extremely slow and unresponsive, and
quickly comes to need a hard reboot. So, I tried all the options (I
think) from the s2ram page above, both under X, and using
init=/bin/bash. Using console mode only, I found:
-f no screen on wakeup (no)
-f -a1 abc superslow mode (slow)
-f a2 slow
-f a3 slow
-f -p -m no
-f -m no
-f -s slow
-f -p no
-f -m -v slow
-f -m -v slow
Note that I rebooted after each attempt, to make sure the errors didn't
compound on each other. I also tried (I think) every option with vga=0,
I'd be happy to try other options, or to retry something specific (I
*tried* to cover all the possibilities, but there are many ;-), but
given that the machine seemed to sleep / resume just fine under suse
10.1, and now it *does* wake up, but it's just realllly slow, I thought
I'd consult the developers to see if I'm missing something, have found a
new one, of if there's something else I can try.
Thanks in advance for any assistance you can provide.
Cheers,
Neil Verplank
