Summary: Suspend issue on ancient asus A7V system
Product: ACPI
Version: 2.5
KernelVersion: 2.6.25
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Sleep-Wake
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Distribution: debian etch
Hardware Environment: asus A7V motherboard, athlon thunderbird 950 CPU
Software Environment: debian etch i386
Problem Description: System powers back up immediately after suspend-to-ram.
Worked around by running echo PWRB > /proc/acpi/wakeup
Steps to reproduce:
After booting the system, any attempt to suspend to ram results in the system
suspending (I can hear the fans go off), but resuming immediately.
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, the system has been like that since I first
got suspend working.
If I run echo PWRB > /proc/acpi/wakeup a second time,
1- The kernel complains again, "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 *enabled
PCI0 S4 enabled no-bus:pci0000:00
USB0 S4 disabled pci:0000:00:04.2
USB1 S4 disabled pci:0000:00:04.3
3- Any attempt to suspend to ram will once again result in the system
suspending and resuming immediately.
