[Ted Felix]

I can't reproduce this in Trusty.  Can you see if you can reproduce this
in Trusty (14.04)?

Title:
  Power button causes unclean shutdown

Status in “acpi-support” package in Ubuntu:
  New
Status in “acpid” package in Ubuntu:
  New
Status in “systemd” package in Ubuntu:
  New

Bug description:
  I noticed that with Ubuntu Server 13.10 when I press the power button,
  it flashes "acpid exiting" on the console and then does an immediate
  hard poweroff. Filesystems are not umounted and require recovery on
  restart.

  Upon further investigation I found that apparently both acpid and
  systemd-logind attempt to handle the event with the described result.

  Disabling either acpid (by deleting /etc/acpi/events/powerbtn) or
  systemd (by adding HandlePowerKey=ignore to /etc/systemd/logind.conf)
  fixes the issue.

  Note: I was reproducing the issue using clean 13.10 server installs in
  KVMs. http://superuser.com/questions/677331/unsafe-power-off-on-power-
  button-pressed/746841#746841 indicates that others have observed this
  with non-VM installs.

  Also #1219338 and #1245327 may be related.
