I had a strange thing happen today. I was using Google Navigation just to display the roads and traffic (no destination entered), and it suddenly backed out to the destination selection screen, and then back to Car Home - as if I had pressed the Back button. I'm using the 1.1GHz LV kernel, set at 250MHz min, 1100MHz max, and OnDemand governor. I then set the max to 900MHz, and tried again and could not reproduce the behavior. However, after changing back to 1100MHz, the behavior quickly reappeared. After at least 5 attempts at each max speed, the behavior qould quickly appear at 1100MHz, but not appear at all at 900MHz. I'm wondering if navigation is causing the CPU to run at max speed, resulting in a heat issue, or if something else is going on. Aside from these specific circumstances, my OG Droid seems be happy with the 1.1GHz kernel set at top speed. Anyone else experiencing odd behavior like this?
