Last night about 10pm, upwind's serial boards crashed again.  "adn/aup" worked, but crashed again after ~10min.  I "reboot"ed from the apartments and got it working.  However, the usbdrive wasn't working this morning, so it probably died in the reboot.  About 9:30 this morning, I cycled power on upwind and all seems well at the moment.

We would change this serial board, but it isn't clear to us which board to swap with.
