I have an i386 system working: FreeBSD d820.flick.local 8.2-PRERELEASE FreeBSD 8.2-PRERELEASE #2 r216091: Wed Dec 1 18:06:20 CST 2010 root@d820.flick.local:/usr/obj/usr/src/sys/D820 i386 Just built the kernel and ran through some tests on the DTrace wiki page. Incidentally, I had a tough time on my system running HEAD built with clang. DTrace simply would not run properly until I built the kernel with the base gcc. It was as if the kernel and userland were not in sync, no matter what I tried (even netstat didn't work). Maybe you need to clean EVERYTHING, checkout a clean source tree (if you've been mucking around in there), and rebuild and install kernel and world. I wish I could help more, but I'm still just a newb in a lot of respects... -Brandon
