[Bug 592047] [NEW] wl driver is in unusable state after suspend

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

= Expected =
   Wireless Network to reconnect fine after suspend. 

= Actual behaviour =
   Network manager is claiming password is not valid for wireless network, wpa_suppliant in debug mode compaints about various errors, like WPA MIC and ioctl errors, causing not to be able to connect.

= Debug output to for workaround =
  - I have stopped the network manager; 

    /etc/init.d/network-manager stop

  - I have killed any remaining wpa_suppliant instances;

    killall -KILL wpa_suppliant

  - I have started the wpa_suppliant in debug mode;

    sudo /sbin/wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd -t 2>&1 | tee -i /tmp/wpa_supplicant.log
 
  - I have included my Terminal output in the logfile was well;

    export PROMPT_COMMAND='history -a; history -r; logger -t Terminal
"`tail -1 $HOME/.bash_history`"

  - I have poked-it-with-a-stick to get it working again using various
instances of rmmod modprobe, ifconfig, iwconfig, tcpdump but this method
is not reliable and cannot be reproduced every time.

= Most interesting messages to me =
When looking at the logfile there are a few messages which worries me the most, but I cannot deduct any logical or workaround based upon them:
   
   - WPA: Could not verify EAPOL-Key MIC - dropping packet

   - ioctl[SIOCGIWSCAN]: Invalid argument

   - ioctl[SIOCSIWAP]: Device or resource busy
