I think the board crash is a thermal related issue -- after leaving the board off for a period of time, ~15min. It booted and successfully completely apt-get update.

After leaving it alone for some time, the same thing happened and I checked the temp and it seemed pretty warm. I have the heatsink on but no fan running over it. It seems the new image uses more power for perhaps more performance and more thermal output?

At least that solves one problem.



I'm still unsure why no USB devices are detected -- has to be related to software/drivers in the Parabuntu image.. any ideas?

I recently had the same thermal "issue" experience during a hackathon. After having the board powered (with all cores running infrequently) for over 7 hours the board just quit and I had to let it cool off 15 minutes.

As has been documented a number of times, you should have a fan blowing across the heatsink. A small fan will work. You can also void your warranty and disable the thermal daemon, if you want.
