In my case, here is a scenario to reproduce it. - Have the laptop configured to suspend upon lowering the lid. - Suspend the laptop with other means, such as <fn><suspend key>, going through the Unity menu or on a terminal sending 'sudo bash -c "echo mem >/sys/power/state', - Immediately after the previous step, before the computer has actually suspended, close the lid.
This sequence of events sends two 'suspend' signals. Thus when resuming from the first one, the system suspends again. The fix: The kernel / OS should ignore a suspend/hibernate/poweroff request if any of these is already in progress. -- 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/1238678 Title: Double suspend to ram and system malfunction after 2nd sleep. Status in linux package in Ubuntu: Confirmed Bug description: After one or two successful suspend-to-ram cycles the system wakes up and immediately goes back to sleep. After this double suspend, some systems like rfkill, for example, will only work after a reboot. Steps in which I can consistently reproduce the bug: 1. suspend to RAM; 2. Wake up the computer; 3. Repeat 1. and 2. two or more times (sometimes is one cycle, sometimes it's two cycles and I even went 4 cycles without incidents only to have this behaviour on the 5th.) The double suspend behaviour seems to happen more consistently if a long time (a day or so) goes by between the suspend and the resume.
