That mystery reboot happened when I was only a few feet away (one or two meters?), in the same room, within hearing distance of the sounds, so I was able to attend to the reboot, what the computer booted into. Also, I have Intel Sandy Bridge system and had read that I needed to upgrade to STABLE or HEAD to get the graphics updates. So I switched from RELENG_9_0 (9.0-RELEASE + patches) to RELENG_9 (STABLE), without asking on the emailing list, and that solved the problem. Tom
