[Bug 1238678] Re: Double suspend to ram and system malfunction after 2nd sleep.


Same problem Ubuntu 14.04 LTS running Unity.  I cannot figure out what
are the two systems that compete with the lid going down.  Workaround
consist at suspending manually and waiting for suspend to complete
before closing the lid.

  Double suspend to ram and system malfunction after 2nd sleep.

Status in linux package in Ubuntu:

Bug description:
  After one or two  successful suspend-to-ram cycles the system wakes up
  and immediately goes back to sleep. After this double suspend, some
  systems like rfkill, for example, will only work after a reboot.

  Steps in which I can consistently reproduce the bug:
  1. suspend to RAM;
  2. Wake up the computer;
  3. Repeat 1. and 2. two or more times (sometimes is one cycle, sometimes it's two cycles and I even went 4 cycles without incidents only to have this behaviour on the 5th.)

  The double suspend behaviour seems to happen more consistently if a
  long time (a day or so) goes by between the suspend and the resume.
