Did this work properly with any previous kernels
and this is a regression, or as far as you know it never worked?

Is there an indication that the system suspended?
Ie. is there an a suspend LED that is blinking or illuminated
when it normally isn't after a regular shutdown?

> /usr/sbin/s2ram not found, falling back to echo.
I don't know what this is about, but would be interested to know
if you simply use this, what happens:

# echo mem >/sys/power/state
Comment 2 Zhangfan 2006-08-10 06:10:26 UTC
It doesnt work under any old kernel。
when using kernel- or kernel-2.6-15.6 which realsed by Magic Linux.
Suspend 2 mem donest work,the LCD Panel was blank,but Suspend led on my Laptop
illuminated,never blinking.....
It never worked

when using kernel- realeased by kernel.org,
Supsend 2 mem done,but screen is still black when wakeup!

when normally shutdown,the suspend led will off
when normally suspend to memeory suspend led wll blinking

> /usr/sbin/s2ram not found, falling back to echo.
This is a command ,bin, with suspend-script package realeased by SUSE

# echo mem >/sys/power/state
I simply use this,suspend to memory is done,suspend led is blinking
but when I push any key to wake it up,my computer restart 

Comment 3 Zhangfan 2006-09-19 18:39:32 UTC
Oh,when after suspend to ram ,
I push power button of my laptop,
It still restarted,no wakeup!
not only power button,when user windows xp,I can press any key to wakeup from
acpi s3,
waiting for solution
Thx ^_^
Comment 4 Len Brown 2007-09-06 15:18:35 UTC
Is this still a problem in linux-2.6.22.stable or later?

Comment 6 Rafael J. Wysocki 2007-09-19 16:46:09 UTC
Can you please try s2ram (http://en.opensuse.org/s2ram)?
Comment 7 Natalie Protasevich 2007-10-22 23:34:54 UTC
Zhang Fan, did you get chance to test with latest kernel (2.6.23+)? and how about #6?
Comment 8 Rafael J. Wysocki 2007-12-12 16:58:19 UTC
Zhangfan, please test the current mainline kernel and report back, thanks.

[I'm going to close this bug if there's no response in two weeks from now.]
