[ Solved below]
I'm trying out the latest beta 195.22 driver, and am experiencing an almost immediate hard-lock after bringing up X. This is on a 9800GT, but another of my systems with an older 6800 works fine. This hard-lock occurs anywhere from 1-15 seconds after x starts. I've tried running the nvidia-bug-report.sh script in that time, but something is that script causes it to lock up immediately, and I can't get a saved log file from it. Attached is a log from nvidia-bug-report.sh while using the "nv" driver, hopefully it'll still have enough info for you
BTW Running FreeBSD 8.0-Release, tried this on amd64 and i386 versions, doesn't make a difference. On this system the older drivers worked great on FreeBSD 7.x.
