Lock reversal and wi failure

On a newly CVSup'd and built system, I'm seeing the following:  After a
few minutes of use (not always the same length of time, nor packets passed),
my D-Link DWL-650 stops transmitting.  The "associated" light stays on,
and a tcpdump of the radiolink continues to show 802.11 packets passing.

However, any network traffic above that level is not seen.  I'm 
currently using a Orinoco Silver and have not seen a similar failure.

Here's some output....
