Hi!
I have two machines: first - win2k with CSR USB dongle (BlueTake) and second - linux
with Ericsson's ROK101008 starter kit.
I'm trying to connect to linux bluetooth-serial-port from win2k.
Just after receivig SABM frame I got such info:

and I found that the 2.6.6 has still a module reference count bug in the
RFCOMM layer. To prevent this bug you must start at least one service
that uses RFCOMM.

I've never seen this before and actually I don't know why get a NULL
pointer dereference here.

Ok, I've just upgreaded to 2.6.6-mh1.
Now, I can't even hciattach my device :/

and here is the problem. Your kernel is buggy and you should better use
the latest 2.6 kernel with our Bluetooth patch. For exmaple 2.6.6-mh1.
