Yes, the output of 'lsmod|grep alx' is indeed empty. Since my system doesn't have wifi, I don't think anything WPA related could be the cause. I ran the commands anyway:
sudo wpa_cli suspend ; sudo systemctl suspend; sudo wpa_cli resume and it has no positive impact. The output of wpa_cli is: "Failed to connect to non-global ctrl_ifname: (null) error: No such file or directory" ** Attachment added: "pm-suspend.log" https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1450396/+attachment/4408960/+files/pm-suspend.log -- 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).
