Some progress: After I failed to identify the responsible hook by running them before 'systemctl suspend' I had the idea to test vice versa if I would be able to reproduce the undesired wakeups with pm- suspend by successively disabling its hooks (=moving the files in /usr/lib/pm-utils/sleep.d to another directoy).
And I was successfull: The hook that seems to be responsible for correct suspend on my system is 00powersave. If all other hooks are enabled except this one, the bug also appears with pm-suspend. And on the other hand if 00powersave is enabled (even if it is the only hook enabled), I was not able to reproduce the bug with pm-suspend. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1450396 Title: Gigabyte P35-DS3: does not stay suspended Status in linux package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Incomplete Bug description: Hello, using Suspend-to-RAM on my system has stopped working reliably on Vivid when booting with Systemd. When I try to suspend my PC the following happens: - PC turns off - PC unwantedly wakes up (turns on) by itself again. This time span until it turns on again can reach from a second (almost immediately) until two or three minutes. - In a few cases (<25%), the PC stays suspended properly. A way to workaround this problem is to boot my PC with Upstart instead of Systemd, then this problem never happens (and has never happened in any of the previous Ubuntu versions since 2008). Thus it seems to be a bug somehow related to Systemd. Other steps I have tried to solve the problem (without any success): - Checking BIOS settings, all options are set that way that the PC should never wake up by any event other than pressing the power button. - Checking by running "cat /proc/acpi/wakeup | grep enabled" if any device could cause wake up events. This lists my USB controller, but deactivating it (with commands like "echo USB0 > /proc/acpi/wakeup") had no success on the problem. Also suspend while running Upstart works fine despite the USB controller listed as "enabled". In the system logs I could see no hint what causes the undesired wake- ups. Allthough there is one factor which seems to have a certain influence: If I close programs like Pidgin, Skype or Firefox that cause continuous network traffic, the chance is higher that my PC will stay suspened (while runinng Systemd).
