** Description changed: Regression: My laptop has become unable to enter S3 sleep/suspend. (A.K.A. Suspend to RAM) It seems to go through all the motions, including shutting down network interfaces and stopping the hard disk, but fails at the last moment and immediately starts back up again, showing the lock screen. 4.15.0-58-generic is affected. 4.15.0-55-generic is NOT affected. In /var/log/syslog, it seems that the cause might be that a USB device fails to suspend. (Log excerpt attached.) - There are no external USB devices connected when the bug occurs. There - are USB devices integral to the laptop and always present, none of which - are new or changed. + The bug occurs both with and without external USB devices connected. + There are USB devices integral to the laptop, which are always present. + + Laptop model: CLEVO N350DW + Processor: 4x Intel(R) Core(TM) i5-6600T CPU + BIOS date: 05/26/2016 + BIOS version: 5.11 ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-generic-hwe-16.04 4.15.0.58.79 ProcVersionSignature: Ubuntu 4.15.0-58.64~16.04.1-generic 4.15.18 Uname: Linux 4.15.0-58-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.19 Architecture: amd64 CurrentDesktop: KDE Date: Thu Aug 22 15:05:09 2019 EcryptfsInUse: Yes InstallationDate: Installed on 2016-09-16 (1069 days ago) InstallationMedia: Kubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) SourcePackage: linux-meta-hwe UpgradeStatus: No upgrade log present (probably fresh install)
