Hi, Tomas
    Will you please add the boot option of "acpi_sleep=s3_beep" and do the following test?
    a. kill the process which is using /proc/acpi/event( use the command of "lsof /proc/acpi/event" to get the process ID)
    b. dmesg >demsg_before; echo mem > /sys/power/state; dmesg >dmesg_after; sync;
    c. After the system enters S3 state, please press the power button and see whether the beep voice can be heard.
    If there is no beep voice, please reboot the system and check whether there exists the file of "dmesg_after".
    
    Thanks.

Comment 7 Zhang Rui 2009-01-11 17:49:32 UTC

is this a regression? i.e. did S3 ever work on this laptop?
could you give a detailed description about the symptom please?
i.e. what kind of broken? hang when suspending? hang when resuming? reboot?
can you see the screen? can the keyboard/network?

As far as I know, S3 never works correctly,

Detailed description:
Suspend worked properly in all cases. First resume after suspend worked in 10% of cases fine, but in the rest of cases hang, screen will not show (even LCD backlight isn't set, you know LCD is completely dark). If I try restart X (Ctrl+Alt+Backspace) at least the LCD backlight is set. Than after approximately 10-15s follows reboot, before reboot in this 10-15s the CPU fan increase turn.
Back to correct resumes (10%), the next resume after suspend, ends with the same behavior like above.

I hope you got it, if not please let me know.

To ykzhao (#6) I'll try this test later today.

Hi, Tomas
    Thanks for the test.
    From the test it seems that the system is resumed from S3 when the power button is pressed.
    What kind of broken on your box? Keyboard/mouse? Or there is no screen?
    Thanks.

No screen.

Thanks Yakui.

Hi, Tomas
    Thanks for the confirmation. Now this is S3 video issue related with ATI graphics driver.
    The S3 video issue is already fixed in intel graphics driver. 
    
    Do the ATI guys have an opportunity to look at this issue? There is no screen after suspend/resume.
    thanks.

Comment 15 Zhang Rui 2009-01-13 00:58:39 UTC

vbetool or boot option acpi_sleep=s3_video may also help in this case.
But anyway this is a drm issue (the same problems on intel graphics are fixed by intel drm driver) rather than ACPI one.

Comment 16 Tomas Pelka 2009-01-13 01:27:15 UTC

Ok I'll wait verdict from ATI guys.

Zhang, Yakui thank you very much for your effort to help me.

I am afraid that this doesn't help. I tried, I think :)
But I'll try again.

Closing as obsolete, if this is incorrect please update the bug having tested versus a recent kernel
