** 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.
