This is from /var/crash.  The vmcore is quite badly corrupted.

I've just noticed that I had USB_DEBUG="yes" set.  I'm trying a
kernel without that set just in case that tickles an issue.

It's been ages (2 years or more) since I used this card so a binary
search is nearly out of the question.  I'm trying to ressurect it
because I got a new laptop with a totally useless new iwn(4) "Centrino
Advanced-N 6235" card in it that can't do 40MHz channels and can't
stay connected to a 20MHz channel for longer than 15 minutes at a
stretch.  And, the antenna cables have w-FL connectors so I can't
just replace it with a good old AR9285.  I'm not sure I'll be able
to desolder the w-FL connectors and move them to my Atheros card
without destroying them.

I'll try to capture some more useful debugging data, but it blows
up pretty badly when the card is inserted.
