It does seem that adding all ptypes and all events filter in kernel ['ala hcidump in user-mode] I am able to catch in the events and do get my recvmsg called - unfortunately kernel panicked [may not be a BT issue et. all - just may be i am poor at pointers].

I just want to know, how do I safely implement _send and _recv HCI socket functions in my kernel module ?
