FreeBSD freebsd.loneowl.net 6.0-RELEASE FreeBSD 6.0-RELEASE #0: Thu Nov 3 09:36:13 UTC 2005 root@x64.samsco.home:/usr/obj/usr/src/sys/GENERIC i386
>Description:
I installed FreeBSD 6.0 today(discs from FreeBSD Mall), and after making a clean install, I went to get things up and reconfigured. I ran vim on the README.txt file on disc 3 of the install, through ssh, and before it was done, I recieved a kernel crash. I read it, pressed a key, I think it said it'd make it abort, and it rebooted. Here's the contents of the /var/crash/info.0 file. There's a backtrace from kgdb below it.
