[Bug 1352379] Re: Network broken after resume

 

Jaap van Ginkel, thank you for performing the requested test. The next
step is to fully reverse commit bisect the kernel in order to identify
the fix commit. Could you please do this following

Title:
  Network broken after resume

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  After a first suspend, it takes ~60 seconds for one to be able to login. We use Dell Optiplex 7010 machines in our student lab. Because of the LDAP authentication, networking is required for authentication. So, restarting network-manager is not an option. I have tried numerous things, such as creating a file /etc/pm/config.d/network-resume with the content:
  "SUSPEND_MODULE="e1000e"

  However, this seems to break the suspend functionality. When manually
  entering "suspend" it goes directly to the lock screen.

  I also tried creating a file /etc/pm/sleep.d/network-resume with:
   #!/bin/sh

  case ${1} in
   resume|thaw)
   nmcli nm sleep false
    ;;
  esac

  Once resumed networking is disabled, and thus I cannot log in.

  * creating a file in /etc/pm/sleep.d with

  #!/bin/sh

  case "${1}" in
          resume|thaw)
          restart network-manager
                  ;;
  esac

  Outcome: Manually suspending works, resume only works when pressing
  the power button. Once resumed the networking is still disabled, and
  thus I cannot log in. After about a full minute networking is restored
  and I can log in.
