For the last two hours, upwind's serial board has been crashing. I've lost count of the number of adn/aups and reboots I've done. Last I checked, it stayed up for more than 3 minutes, so I'm going to bed.
If it helps to diagnose this:
1. The last 3 nights, these failures ocurred in the 10pm-12am timeslot. sonic temps dropped from 29 to 25C during this time.
2. I had rserial running several times during these failures. It would appear that the data rate slowed down and became erratic (like dropped samples) beginning one second to half second before the crash.
