Public bug reported: Hi,all I'm using latest kernel 4.1-rc3 on ubuntu 14.04.2 LTS X86_64, and I found that, after resuming from suspend-to-memory, the systemd-shim deamon will execute a 'poweroff', which shuts the system down.
here's my step to reproduce the bug: 1.echo mem > /sys/power/state //ok 2.wait for 30 seconds //ok 3.push power button //ok 4.system resumes automatically //ok 5.after a few seconds, system shutdown //oh no... I replace /sbin/shutdown with a script that prints the current process backtrace by pstree, then the system will not halt after resumming from suspend-to-memory. Here's my script: # cat /sbin/shutdown #!/bin/sh pstree -a > /home/chenyu/shutdown_trace.log and here's the backtrace when system is executing my 'shutdown', after resumming, we can see that, systemd-shim invokes 'sh -c /sbin/poweroff': init |-ModemManager | `-2*[{ModemManager}] |-NetworkManager | `-3*[{NetworkManager}] |-acpid -c /etc/acpi/events -s /var/run/acpid.socket | `-sh -c /etc/acpi/powerbtn.sh |-anacron -s |-avahi-daemon | `-avahi-daemon |-bluetoothd |-cron |-cups-browsed |-cupsd -f | `-dbus dbus:// |-dbus-daemon --system --fork |-getty -8 38400 tty4 |-getty -8 38400 tty5 |-getty -8 38400 tty2 |-getty -8 38400 tty3 |-getty -8 38400 tty6 |-irqbalance |-kerneloops |-login -- | `-bash | `-sudo -s | `-bash |-ondemand /etc/init.d/ondemand background | `-sleep 60 |-polkitd --no-debug | `-2*[{polkitd}] |-rsyslogd | `-3*[{rsyslogd}] |-sshd -D |-systemd-logind |-systemd-shim | |-sh -c /sbin/poweroff | | `-shutdown /sbin/shutdown -h -P now | | `-pstree -a | `-2*[{systemd-shim}] |-systemd-udevd --daemon | |-systemd-udevd --daemon | |-systemd-udevd --daemon | |-systemd-udevd --daemon | |-systemd-udevd --daemon | |-systemd-udevd --daemon | |-systemd-udevd --daemon | |-systemd-udevd --daemon | |-systemd-udevd --daemon | `-systemd-udevd --daemon |-upstart-file-br --daemon |-upstart-socket- --daemon |-upstart-udev-br --daemon `-whoopsie `-2*[{whoopsie}] Since I'm not sure why systemd-shim act like this, I would be happy to debug with your suggestion, and give feedback to you.
