If this is how I got most of my panics, this little script running in two different xterms helped decrease the time to panic. It got my system to panic a lot with the older nvidia drivers. #!/usr/local/bin/zsh # Try with and without. export __GL_SINGLE_THREADED=1 /bin/rm -f glxinfo.core while [ 1 = 1 ]; do /usr/X11R6/bin/glxinfo >& /dev/null if [ -e glxinfo.core ]; then echo "Core found." /bin/rm -f glxinfo.core fi done This always helped get my system unstable on 4-STABLE rather quickly. I think it was the issue of running two or more GL programs at the same time that caused or increased the problem.

The sad thing is that almost any type of bad hardware can cause stability issues. At least this is what I was told.

You should not be mixing the FreeBSD AGP and the nvidia AGP together. Choose one or the other. > If you want me to get any information from the dump or try anything > please let me know.

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? :) Sean ----------------------- sean-freebsd_at_farley.orgReceived on Mon Aug 23 2004 - 19:26:18 UTC
