forget whatever I told you to handle this inside L2CAP. It is nearly
impossible to get the locking for this right. I crashed my Quad G5
multiple times today.

So I went back to fix this inside the HCI layer. You can apply the
attached patch on top of 2.6.18-mh3 and it should give you concurrent
connect support for all protocols.
