Hi...
I had my -stable machine reboot twice today, and figured that I'd
check in and see if maybe this was a known problem...my first thought
is the land attack stuff, or FOOF, and I'm just too behind on my kernel :(
I've downloaded the newest kernel, and will be upgrading tomorrow, but
if its not related...?
Here's what GDB is showing me:
