Lately, I have been able to spontaniously reboot by running five GL applications at once. Which isn't pleasant but doesn't concern me too much. Each time I've had a panic there has been only one gl application running... and lately all GL programs are causing this issue. > Are you using the latest nvidia drivers? As a matter of fact, that is what I think caused the problem. I just upgraded to the latest drivers on the 19th... right before I had these problems. That combined with the fact that all of these issues can be consistently caused by running gl programs gives me strong cause to suspect it. > You should not be mixing the FreeBSD AGP and the nvidia AGP together. > Choose one or the other. Yes, I suspect this might be part of the issue. I don't remember seeing this message before the new driver was installed. But I do know that the old kernel had it loaded (it was hard coded with the configuration file). I think the driver might have changed the way it handled the presence of both AGPs. > I have my own panic on 4-STABLE which I just reported in freebsd-stable: > http://lists.freebsd.org/pipermail/freebsd-stable/2004-August/008530.html > Would you like to trade? :) lol, I would love to... if I thought I could help. But I am still learning as much as I can about the kernel... nowhere near the level required to help. Kevin -- "Down with disease, up before the dawn.
