I don't know if the first panic was a bad pte error since the machine was running headless. > > For hardware, you can try memtest86+ to check to make sure the new > memory is good.

I kinda wondered if heat might be an issue, since it was kind of tucked away in a spot with bad airflow. I'll try the memtest thing. Is there a way to get the CPU temp in FreeBSD? Meh. let's see if this thing'll actually compile... Thanks, Micah Matt
