The machine appears to suspend, and this is confirmed in syslog. However, when attempting resume, the screen is black and there is no indication of resumption. The machine automatically reboots within ~15 seconds. I did this three times with -31. Reverting to the -28 kernel restored suspend/resume. --- ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: reece 2194 F.... pulseaudio /dev/snd/controlC0: reece 2194 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 16.04 HibernationDevice: RESUME=UUID=3329049e-5384-42bd-beaa-c81181926a01 InstallationDate: Installed on 2016-05-11 (65 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) MachineType: Dell Inc.
