I have been receiving kernel panics a few times in the past few months, but each time I have noticed it is when I am connected to the internet through Bluetooth PAN to my iPhone. Most recently, the panic happened while opening pages through handoff on my iPhone.

Are there any thoughts on what is causing this? More specifically, if I do not have any kernel extensions installed (as per log) except ones that start com.apple.... (Except nosleep, which doesn't seem to be involved at all, as I wasn't using it) does that suggest that I have a hardware problem?
