Bug Description

As I am working on the integration of the raspberry pi with some bluetooth devices, I am experimenting to connect devices HC-05 via bluetooth to the raspberry.
I'm using this with rfcomm and bind the /dev/rfcomm device to a bluetooth address of the HC-05

When sending and receiving data , it works well, until the communication stalls. See the stall messages in the kern.log.

When powering down the HC-05, the raspberry pi became unavailable.

I noticed the system completely crashed and had to be rebooted. See attached kern.log

Apparently bluetooth usage on Linux is not an easy task.

Some suggestions ?
