Title:
  Reboot when resume from suspend

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  When I resume my computer from suspend2ram, after about 2 seconds it
  shutdowns and after about 3 seconds swithces on, and system starts to
  boot from GRUB as it was poweroff.

  But if I resume my computer right away after it was suspended, it
  resumes properly. I occur this problem if some amount of time passed
  between suspend and resume.

  And I didn't reproduce this problem when lightdm was stopped (but the
  screen is black after resume, but I can login via SSH). But with
  launched X Server the problem occurs both with nouveau and Nvidia
  proprietary driver.

  There is not this problem on Ubuntu 14.04 (it is installed on this
  computer too but without madm and root partition encryption).
