[Bug 1184262] Re: times out too early, stuck in PrepareForSleep, causing network and other services to not resume

Hello Catalin,

thanks for your feedback!

Interesting, thanks for pointing that out. If it can be confirmed that
this now only happens if you close the lid, then this indeed deserves
a new bug report, or perhaps it's the same issue as Gabriel has in bug
1252121. I'll ask there, too.

It would also be interesting if you ever get a suspend failure with
this:

  sudo gdbus call -y -d org.freedesktop.login1 -o
/org/freedesktop/login1 -m org.freedesktop.login1.Manager.Suspend true

This should ideally be equivalent to running pm-suspend or the
menu/power button, but it is only sometimes equivalent to closing the
lid. The lid is handled by logind internally *unless* there is a
running Unity/GNOME session. On some laptops there are pm-suspend
quirks which switch to VT1 before suspend, which might be related.

Bug description:
  After a suspend/resume, network-manager claimed that wireless was not
  available and would not let me reconnect to the wireless here.
  'iwlist wlan1 scan' would also not work; so thinking that it was a
  driver problem, I rebooted the system.  When it came back up, nm-
  applet in lightdm claimed that networking was disabled, and the option
  to enable it was greyed out.  It could also not be enabled by nmcli.
  I ended up stopping network-manager, bringing up the interface via
  /etc/network/interfaces, and logging in... at which point, restarting
  network-manager *did* let me enable networking from my logged-in
  session.

  So there are several problems here:
   - after a reboot, network-manager claimed networking was disabled.
   - nm-applet is not letting me enable networking from the lightdm session.
   - the networking was failing after a suspend/resume cycle, and could not be enabled even from inside the user session.

  The last issue probably *was* a kernel driver problem; but the first
  two issues are network-manager problems of some kind.

  SRU INFORMATION:
  ----------------
  Reproducer:
  - Force suspend to take very long by adding a sleep:
    echo -e '#!/bin/sh\nsleep 15\nexit 1' | sudo tee /usr/lib/pm-utils/sleep.d/00break
    (this will also make suspend fail, which eases testing)
  - Suspend from the menu or with
    sudo gdbus call -y -d org.freedesktop.login1 -o /org/freedesktop/login1 -m org.freedesktop.login1.Manager.Suspend true
  - With the 13.10 final version, systemd-shim will (often) time out, and the next Suspend call from above will fail with "Operation already in progress" and the network does not come back up. With the fixed version, network should be back up and the Suspend() call can be issued many times.

  Fix:
    https://github.com/desrt/systemd-shim/commit/136ed1143077d13c2
    https://github.com/desrt/systemd-shim/commit/16a7fdc0652ad78f4

  Regression potential: Errors in this code could potentially break
  suspend/shutdown completely, so for verification both of these
  functionalities ought to be tested on real hardware.
