I was having a similar problem with FreeBSD 6.0-RELEASE whereby the system was totally stable without SMP, and totally stable with SMP while X wasn't running, but where the system would hang after between zero and 5 minutes of running X. Sometimes it would lock up even before X got started. I'm running a dual Athlon system on an Asus A7M266-D. I fixed the problem by removing modules in /etc/X11/xorg.conf and found that removing: Load "dri" from the "Module" section stopped the freezes, and returned my system to full stability. I don't know what the dri module does, so I don't know what I'm missing, but everything seems to run okay now. Just in case someone else encounters the parent post with the same problem, - Jason Barnes
