Hi, I can reproduce this reliably with simple dd if=/dev/da0. At the end external USB drive turns off the lights (tough it still spinning) and system fall into the state where it is impossible to reboot it cleanly. I can get drive back only after full power cycle (simple reboot is not enough). Using same drive under moderate load seems mostly to work. It also is used to work under 7.2. Anyone have an idea what this could be?
