Scott, I wanted to thank you for your help. I do in fact have an Asus motherboard. Your tip on modifying the i686_mem.c file worked, and X stopped rebooting my machine :-) My processor has seemingly stopped time traveling, too :-) Thank you very much for your quick, clear, and courteous assistance.

There are still some problems with it, usually with the symptoms you describe. http://www.freebsd.org/cgi/query-pr.cgi?pr=28418 Hrrmm--I see that it seems to be resolved as of two days ago--sigh, this means I'll have to do a buildworld and see if it works without adjustment. The fix has been to open up /usr/src/sys/i386/i368/i686_mem.c Around line 269 you see u_int cr4save; mrd = sc->mr_desc; Between those two lines, insert a line return; So it'll now look like u_int cr4save; return; mrd = sc->mr_desc; It has to do with MTRR problems (This trick was given me by Bill Triplett in case he sees this post and wonders if I've forgotten--Hi Bill. :) ) This of course, assumes you have an ASUS Then, you have to recompile your kernel cd /usr/src/sys/i386/conf config MYKERN You will then see the thing something like source is ../../compile/MYKERN Don't forget to do make depend So cd ../../compile/MYKERN make depend; make; make install Reboot and you should be good to go. (You probably know all that, but I have it kept on my hard drive as a web page so am cutting and pasting--I'm really sleepy--sorry for the extraneous info) HTH Scott To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
