I just had a scary moment. I was running titan's latest from apps-testing earlier today. Suddenly, I rebooted, first time that had happened. No warning or indication that anything funny was going on. I was running at something like 810 mHz, because 800 wasn't available. I couldn't get back in, had to reflash the kernel with an earlier 800 mHz kernel. Edit: I flashed again with the ulv version back on i think page 203. I couldn't run it this time, had to reflash again. I had successfully run it before...
