I had a problem on my Gforcce 2MX400 where the first GL app I ran would be ok, but running any GL apps after that would cause a core dump (and sometimes a hard lock of the machine). A problem I noticed, though, was that sysctl -a | grep nv was showing a selected AGP rate of x4. I was able to change that value to x1 by making a change as documented on the Nvidia FreeBSD FAQ page: "Try lowering your AGP rate in the BIOS or nvidia_os_registry.c. If you want to use nvidia_os_registry.c to do this, find the line that reads { "ReqAGPRate", "Force AGP Rate", 4, 0 }, and change the last 0 to 1. Now you will be able to set the sysctl hw.nvidia.registry.ReqAGPRate to the value of the desired AGP rate. You will of course need to rebuild/reinstall/reload the kernel driver before attempting to set the sysctl." This fixed all my problems -- the driver seems to be very stable now. regards.
