[Bug 664625] [NEW] system freeze related to rfcomm

[Johannes Ballé]

Public bug reported:

Steps to reproduce:

1) rfcomm connect 0 <mac>

In this case, we are connecting to a LEGO Mindstorms NXT brick.

2) Turn off brick.

3) After a few seconds, the system freezes.

I did this again in the text terminal and took a picture of the output,
will attach separately.

This did not happen with the stock intrepid kernel (2.6.28-11-generic).
