Hi
Whenever I switch a wifi network, the macbook freeze. It happens every time, it is repeatable.
I have MacBookPro11,3 and using ububtu 14.04 with latest kernel 3.19.0-31-generic
This is the what I see in the log file ( I post to log files, for two times that it happen, I can post more as I can recreate it many times)
