Description Daniel Bornkessel 2005-09-01 16:58:15 UTC 
- Standby: Notebook goes into standby but does not wake up again (screen is
already there). Tried from X.

- Suspend to RAM (1): Stopping tasks seems to be finished, nothing happens
afterwards -- does not suspend. Tried from X and from console with network down
and e100 module unloaded
- Suspend to RAM (2):behaves like Standby. Tried from console (X running, no
modules unloaded)
- Suspend to disk: behaves like Suspend to RAM (1).

Suspend-to-disk fails for me in the same way. My machine is a 1000MHz Pentium
III desktop.
Comment 7 Forgotten User ZhJd0F0L3x 2005-09-05 13:31:12 UTC 
try debugging it as described in
http://www.susewiki.org/index.php?title=ACPI_suspend, this is not a powersave
bug, so the powersave logs are worthless. We'd actually need messages during
suspend (T20 has serial port so this should be easy) if it still fails after that.
Comment 8 Daniel Bornkessel 2005-09-20 11:20:23 UTC 
Suspend to disk works if sound module
snd_cs46xx 
gets unloaded and the SUSPEND2DISK_SHUTDOWN_MODE is set to 'shutdown'.
This can be a problem if applications are activly using the sound device. 
Is there a way to find out which applications are using the device in order to
kill them?
I did an init script which just kills kmix and added that to the 'sleep' config
file ... but this solution is not really clean.
Comment 9 Forgotten User ZhJd0F0L3x 2005-09-20 11:51:52 UTC 
so this is a sound driver bug actually.
Comment 10 Takashi Iwai 2005-09-20 11:56:24 UTC 
It's know that PM with cs46xx on TP doesn't work for a long time...
A better h/w information from IBM would be required to fix this.
Comment 11 Sebastian Voitzsch 2005-10-09 20:55:26 UTC 
Suspend2Disk works well without unloading if you enable the "thinkpad=1" 
module option.  
 
This doesn´t solve the issue that there is no sound output after resume 
without reloading the sound driver; at least /etc/init.d/alsasound restart 
should be executed.

We will not fix this bug for 10.0 anymore.  If the bug still exists in openSUSE 10.3, please reopen and change the product.
