	Trivial deadlock :
	initiating a connection to a device within 80ms of receiving
incomming connection from same device. Unknown if bug is in fw or
stack, but firmware deadlock.

	Intermitent failure :
	Initiating connection (page) within 20ms of bringing HCI
device up. Sometime it works, sometime it doesn't.

	None, as far as I can see. That's why I was looking at other
vendors.

	Thanks for the info.
