help with panic/kgdb

Hi,

First off, let me say it's been a very long time since I've had to deal
with a FreeBSD box panicing, so bear with me.  Tried this on -questions
and no takers.   Not really sure if I've got the right list, my apologies
if this should go elsewhere...

This particular machine has been acting up since I upgraded to 4.8-p18
from 4.8-p6(?).  The only bit of "odd" hardware in it is a 3Ware IDE RAID
card (full dmesg below).  This is the second panic since the upgrade.

My main goal here is to try and figure out if it's a hardware issue (bad
memory, dead CPU fan, etc.) or an OS issue, so anyone that can look at the
gdb output below and give me some insight, go ahead.

Thanks,

Charles

Here's what gdb tells me so far:

If you need me to poke around at any variables, please let me know.  As
you can see, this crapped out during the daily run, I'm assuming the
"find" process that tanked was some part of one of the daily scripts.

Here's the dmesg:
