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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1450396 Title: Gigabyte P35-DS3: does not stay suspended To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1450396/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
