Suspend issue on ancient asus A7V system

Suspend issue on ancient asus A7V system

[Michel Lespinasse]

Hi,

I'm having a minor issue getting suspend to ram to work on an old
asus A7V based system: the system does suspend (I can hear the fans
go off etc...) but it immediately resumes.

I do have a workaround though: After booting, this system shows in
/proc/acpi/wakeup:
Device  S-state   Status   Sysfs node
PWRB      S5    *enabled   
PCI0      S4     disabled  no-bus:pci0000:00
USB0      S4     disabled  pci:0000:00:04.2
USB1      S4     disabled  pci:0000:00:04.3

If I run echo PWRB > /proc/acpi/wakeup,

1- the kernel complains that "ACPI: 'PCI0' and 'PWRB' have the same GPE,
   can't disable/enable one seperately"

2- /proc/acpi/wakeup now shows:
Device  S-state   Status   Sysfs node
PWRB      S5    *disabled  
PCI0      S4     disabled  no-bus:pci0000:00
USB0      S4     disabled  pci:0000:00:04.2
USB1      S4     disabled  pci:0000:00:04.3

3- The system can now be suspended, and it will
   resume normally when I press the power button.

This is not a recent regression, that system has been like that since
I first got suspend working.

Hope this helps. I can collect additional information if you tell me how.

Cheers,

What can you see in /proc/acpi/wakeup if you run "echo PWRB
> /proc/acpi/wakeup" again?

Please open a bug at
http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI
and attach the acpidump output there.

thanks,

Done, bug 10503. No idea if I used the correct component though.

Thanks,
