LOR - ath (similar to LOR #42) on FreeBSD 6-STABLE 2007.04.08.19.20.49

[Parv]

(Before Apr 8 update, I built the world+kernel as of
2007.03.29.21.58.25 UTC.) I am running FreeBSD 6-STABLE as of
2007.04.08.19.20.49 UTC, with ath0 driver for Belkin "My Essentials"
Wireless G card, which I had been using without problems until now.

Some of current configuration is ...

I had not set up dumpdev & large enough dumpdir at the time of above
crap-shoot.  I will update when I LOR happens again.

Yesterday, while in X & having problem connecting to places, namely
hosted by pair.com, computer shut itself down.  I rebooted with a
debug kernel complete with WITNESS* options; just after attaching
the ath0 interface, I was greeted by (sorry, I do/did not have a
serial console setup; I do have some images) ...

  ... there are 4 other images which may be inconsequential (ath0
  attachment messages; output of command 'bt' which seemed to
  produced the same output as above; output of 'ps' & 'x').

Above appears to be, to my untrained eye, similar to ...

Is there anything I could do to generate other|more data?  Is there
a solution for my above LOR?
