[Bug 1252121] Re: missing PrepareForSleep signal after resuming, causing networking to stay disabled

 

Any progress on this issue? I experience all of the symptoms posted by
#8, are more logs required to properly troubleshoot this issue?

The proposed workaround for enabling the network using "nmcli nm sleep
false" works ok for me, but I also use VirtualBox quite heavily and any
running machines refuses to resume due to the missing "PrepareForSleep
false" signal. I can see in the VirtualBox source-code that it waits for
this signal to determine if the host has properly resumed from standby
in order to resume all the guests from a "Paused" state.

Are there any way to also "fake" the sending this dbus-signal via a
sleep.d-script to make VirtualBox happy as a workaround for this issue?

  Uname: Linux 3.12.0-custom x86_64
  ApportVersion: 2.12.5-0ubuntu2.1

  SRU INFORMATION:
  FIX: https://github.com/desrt/systemd-shim/commit/9e1ebe3ab (in trusty already)

  Regression potential: Low. Flushing the session bus was introduced in
  version 4 and is obviously bogus as in a system D-BUS service there is
  no session bus. This causes lots of confusing error messages and
  unnecessary overhead like trying to start dbus-launch. Flushing the
  system bus is low-risk, in most cases it's a no-op and it would
  otherwise prevent losing signals after waking up. No known
  regressions.

  TEST CASE: Run several suspend/resume cycles with the lid, session
  indicator menu, and verify that the network comes back up. It is known
  that this fix is necessary but not sufficient, so it is not expected
  to fix all cases. But it should not make things worse, so if network
  now does not come up any more on a machine where it previously worked
  this would count as failure/regression.
