A few questions for anyone with one of these units:
1) How quickly does it boot up once powered on?
2) Does anything become corrupted if you repeatedly hard power on/off in the middle of ?
3) Has anyone tried wiring it directly to unregulated 12V on the PDP, and driven a robot hard to see if it browns-out or powers off?

1) Fast. Less than 20 seconds. Can be tweaked to go even faster.
2) We haven't seen anything become corrupted but as I have said previously in this thread and others, it's a linux system. Rebooting it repeatedly uncleanly is going to cause some pain with fsck at some point so just be mindful and take necessary steps to avoid it.
3) Not yet. We will be doing that soon. I would recommend a regulator. For this year, the VRM has some 2A points where it could be plugged in and should be fine, assuming the rules allow for that.
EDIT: My one new comment is that after a recent discussion and some more benchmarking and other nonsense, I will add that not all CUDA cores are created equal over at Nvidia. The CUDA cores on the tegras are not the CUDA cores on the graphics cards in your super awesome gaming rig. The bottom line is that extra horsepower is not an excuse for sloppy coding and this is still an embedded system so efficient code is key. Also, memory management between the CPU and GPU has proven to be tricky.
