Hi
Just wanted to see if anyone could give me some feedback as to what
happened, or how to get more info. My machine was just sitting on the LAN
and it panic'd. X was running and it had some ssh's open.
I'm running 4-STABLE from August 3rd.

any way I can get more information from that? I know using a kernel
compiled with -g would help, but how would that be done, because I've
been sup'ing my src every day...
Thanks
Keith
