Now after I leave the board runnig for 45 minutes to 1 hour, the wifi driver starts to cause issues and ifconfig does not work anymore. the bellow log will show that the wifi was working and I did get an IP address but after some time I started to get an error about "hung_task" and then ifconfig did not respond.
I can replicate this 100% of the time.
