Setting SYSTEMD_BYPASS_HIBERNATION_MEMORY_CHECK dos not change anything but this seems logical as this was introduced in a recent version of systemd and does not exist in systemd 229.
Creating a /etc/systemd/sleep.conf with SuspendState=mem (to avoid cycling through different suspending modes) does nto improve things either. When this problem occurs (ie. suspend process started but hanging), I cannot manually write mem to /sys/power/state ; trying to do so fails with a "device is busy" error. ** Summary changed: - Cannot hibernate properly ; systemd-sleep hangs + Cannot hibernate or suspend properly ; systemd-sleep hangs -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1652499 Title: Cannot hibernate or suspend properly ; systemd-sleep hangs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1652499/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
