I just got another USB 3.0 bugreport, the entire system crashed. That particular customer already filed a bugreport in November 2013 that his system is in a bad state when using some USB 2.0 media devices which even have opensource drivers built into the kernel. USB 3.0 support with Linux seems to be a disaster with Linux 3.6.12. The affected board is an Intel DH87RL board.
