Title:
  No network after resuming from hibernate

Status in linux package in Ubuntu:
  Expired

Bug description:
  After resuming from hibernate I have no network connection. This
  doesn't happen with suspend, only hibernate. I'm guessing this is
  something with network-manager as doing 'sudo service network-manager
  restart' fixes the problem. ifconfig shows no eth0 interface but doing
  'ifconfig eth0' does return some info. It's like the interface is down
  or something

  1. Hibernate system (must manually enable hibernate in pm-utils)
  2. Resume from hibernate.

  Expected result:
  Network connection is restored

  Actual result:
  No network connection. network-manager icon in system tray has a red X on it. 
Doing 'sudo service network-manager restart' brings the network back.

I don't know how much this will help. I had to restart network-manager
before it let me collect the data.

[Kernel-packages] [Bug 1397501] Re: No network after resuming from hibernate

2014-12-06 Thread Christopher M. Penalver
Nick B., could you please test the latest upstream kernel available from
the very top line at the top of the page (the release names are
irrelevant for testing, and please do not test the daily folder)
following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow
additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into 
the OS) please make a comment in your report about this, and continue to test 
the next most recent kernel version until you can test to the issue. Once 
you've tested the upstream kernel, please comment on which kernel version 
specifically you tested. If this bug is fixed in the mainline kernel, please 
add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested exactly 
shown as:
kernel-fixed-upstream-3.18-rc7

This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

  1. Hibernate system (must manually enable hibernate in pm-utils)
  2. Resume from hibernate.

  Expected result:
  Network connection is restored

  Actual result:
  No network connection. network-manager icon in system tray has a red X on it. 
Doing 'sudo service network-manager restart' brings the network back.
