Public bug reported:
Network Manager claims my wlan connection is active and properly
connected but I end up with unresponsive applications like thunderbird
and chrome.
My syslog shows the following lines

In order to stop chrome and thunderbird I have to use task manager to kill a
process.
syslog and kern.log grow exponentially in order to log all the stack
traces
However I have no problem if I use eth0 instead of wlan0.
