The box is a Mac Mini, 1.66GHz.  The USB bluetooth adapter is builtin.

>Description:
While `rfcomm_sppd -S -c 1' and sdpd, an attempt to connect to sppd was made from a remote device (a HP iPAQ).  In the same time, FreeBSD page faulted.  I suspect that the attempted connection caused FreeBSD to do so.  However, due to the nature of the operating system the iPAQ runs, I am not completely sure whether the attempt to connect to sppd, or just a SDP query, was made.

>How-To-Repeat:
Trying to connect to rfcomm_sppd from a remote bluetooth device might trigger it, although there might be more conditions and variables I am not aware of.
