Hi Eugene,

> I'll ask a friend and we'll try pan during this week.

first use l2test only and don't load any other highlevel Bluetooth
protocol. I will also try to reproduce it with my test machines. If it
is a L2CAP only problem it is much more easier to find the bug.

This is actually what I already thought, the problem exists only on
incoming connections. The RFCOMM refcounting is a bit more complex,
because it involves the TTY part that also modifies the refcounting. Let
us try to start on L2CAP level and then step by step narrow the problem.

Marcel
