I'm in no way familiar with X. That said: you're using an ATI Radeon card, yet the kernel crashed in agp_nvidia.c. nVidia != ATI. Is it possible that you changed video cards at one point, and you're still using the nVidia AGP driver (loaded via /boot/loader.conf)? dmesg might be useful here. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
