Fair enough. Thanks for the information. I just rebooted into 4.13.0-21-generic. Either it's a lucky boot in which suspend works, or the issue has been resolved.
For those interested, the value of /sys/power/mem_sleep (after a clean boot, suspended once) is: s2idle [deep] -- 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/1738224 Title: Suspend broken after kernel upgrade Status in linux package in Ubuntu: Confirmed Bug description: My machine (XPS 13 9360) won't go into suspend properly after upgrading from linux-image-4.13.0-17-generic to linux- image-4.13.0-19-generic. This affects both suspend through lid close and "systemctl suspend". Screen goes off, power led remains lit. Then after some time the screen comes back on, is stuck and lets me wait for a few before becoming responsive again. Booting back into 4.13.0-17 resolved the issue. --- ApportVersion: 2.20.7-0ubuntu3.6 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: jeffrey 1963 F.... pulseaudio CurrentDesktop: GNOME DistroRelease: Ubuntu 17.10 HibernationDevice: RESUME=UUID=0253ffe9-bdbf-4825-b583-e8055f7bffe5 InstallationDate: Installed on 2017-10-18 (56 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Release amd64 (20171017.1) MachineType: Dell Inc.
