Per #51... The offender appears to be Smart Connect. Smart Connect Enabled, TPM disabled, Rapid Start disabled. System resumed after 24 hours, 5 seconds:
Thu May 22 19:46:27 MDT 2014: performing suspend Fri May 23 19:46:33 MDT 2014: Awake. Happy to test anything else or investigate the lack of the "Disabling Intel Smart Connect" message in #50 if it'll help. -- 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/1318477 Title: [Dell XPS 15 9530] Wakes from sleep after exactly 24 hours + 3-5 seconds Status in Dell Sputnik: New Status in “linux” package in Ubuntu: Incomplete Bug description: Symptoms: The system will wake itself from sleep after very nearly exactly 24 hours, + / - 10 seconds or so. /var/log/pm-suspend.log will show this: Sat May 10 22:08:49 MDT 2014: performing suspend Sun May 11 22:08:54 MDT 2014: Awake. In this case the system has resumed after 24 hours and 5 seconds with no user request to do so. Steps to reproduce: Suspend machine by closing lid. The system can be plugged in to charge while it is suspended, and then subsequently unplugged, but the suspend occurs on battery power, and when the resume occurs the system is also not plugged in. I have not tested other permutations. No other action is necessary. The system will randomly resume 24 hours + 3-5 seconds later. WORKAROUND: Disable in BIOS Rapid Start, Smart Connect, and TPM. --- ApportVersion: 2.14.1-0ubuntu3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: dpoler 2444 F.... pulseaudio /dev/snd/pcmC1D0p: dpoler 2444 F...m pulseaudio /dev/snd/controlC0: dpoler 2444 F.... pulseaudio CurrentDesktop: Unity CurrentDmesg: Error: command ['sh', '-c', 'dmesg | comm -13 --nocheck-order /var/log/dmesg -'] failed with exit code 1: comm: /var/log/dmesg: Permission denied dmesg: write failed: Broken pipe DistroRelease: Ubuntu 14.04 EcryptfsInUse: Yes InstallationDate: Installed on 2014-05-06 (6 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) MachineType: Dell Inc.
