[Bug 1519991] Re: Network-manager freezes system and the song that's playing

 

I found a way to reproduce this bug via terminal!

3. Running 
nmcli r all on / nmcli r all off 

OR running rfkill block wlan / rfkill unblock wlan (then the wi-fi
networks won't appear and you have to run sudo service network-manager
restart)


** Description changed:

  1) The release of Ubuntu you are using, via 'lsb_release -rd' or System
  -> About Ubuntu
  
  Description:	Ubuntu 15.10
  Release:	15.10
  
  2) The version of the package you are using, via 'apt-cache policy
  pkgname' or by checking in Software Center
  
  network-manager:
    Installed: 1.0.4-0ubuntu5.1
    Candidate: 1.0.4-0ubuntu5.1
    Version table:
   *** 1.0.4-0ubuntu5.1 0

       1.0.4-0ubuntu5 0

  3) What you expected to happen
  
  Connection remain stable, without lags and randomly disconnects.
  
  4) What happened instead
  
  a. Wi-Fi randomly disconnects (dmesg shows Reason 3: DEAUTH LEAVING)
  b. Pages doesn't load properly. They load without CSS or without some images.
  c. Network-manager freezes system when I disconnect from my network and freezes the song that's playing (like a DJ hahaha), either in Rhythmbox or Banshee.
  d. Connection becomes unstable after some time, especially after suspend.
  e. Network-manager applet doesn't show available networks after I disconnect, only showing after running "sudo service network-manager restart" command.
  
  ***
  Steps that may help to reproduce the bug:
- 1. Play some music. Enable and disable air plane mode constantly (if you have an air plane button in your keyboard)
- 2. Play some music. Go to "edit connections". Forget the network, wait 5 seconds then enable and immediately disable air plane mode. This doesn't occur always.
- 3. Running nmcli r all on / nmcli r all off

** Description changed:

  1) The release of Ubuntu you are using, via 'lsb_release -rd' or System
  -> About Ubuntu
  
  Description:	Ubuntu 15.10
  Release:	15.10
  
  2) The version of the package you are using, via 'apt-cache policy
  pkgname' or by checking in Software Center
  
  network-manager:
    Installed: 1.0.4-0ubuntu5.1
    Candidate: 1.0.4-0ubuntu5.1
    Version table:
   *** 1.0.4-0ubuntu5.1 0
          500 http://br.archive.ubuntu.com/ubuntu/ wily-updates/main amd64 Packages
          100 /var/lib/dpkg/status

  3) What you expected to happen
  
  Connection remain stable, without lags and randomly disconnects.
  
  4) What happened instead
  
  a. Wi-Fi randomly disconnects (dmesg shows Reason 3: DEAUTH LEAVING)
  b. Pages doesn't load properly. They load without CSS or without some images.
  c. Enable/disable airplane mode or running nmcli freezes the song that's playing (like a DJ hahaha) and boosts the CPU usage.
  d. Connection becomes unstable after some time, especially after suspend.
  e. Network-manager applet doesn't show available networks after I disconnect, only showing after running "sudo service network-manager restart" command.
  
  5) Steps that may help to reproduce the bug:
  1. Play some music. Enable and disable air plane mode constantly (if you have an air plane button in your keyboard).
  
  2. Play some music. Go to "edit connections". Forget the network, wait 5
  seconds then enable and immediately disable air plane mode. This doesn't
  occur always.
  
  3. Running
  nmcli r all off ; nmcli r all on
  
- If the song doesn't freeze, wait for 5 seconds and run this command
- again.
+ If the song doesn't freeze, run "nmcli r all off ; nmcli r all on ; sudo
+ service network-manager restart ; nmcli r all off ; nmcli r all on ;
+ sudo service network-manager restart"
  
  Sorry my english.
