Vexing bug (possibly system watchdog related?)

[Redneck]

We had the exact same problem. It occurred on both wired and wireless communication. After spending an ungodly amount of time trying to debug it, we finally talked to one of the WPILib guys and he said the problem was likely the camera... apparently that task was preventing the communication task from sending data (hence the watchdog timeouts) and the only fix we had was to completely remove the camera code.

We had a periodic system watchdog issue (approx 4 per minute) that I finally traced down to an issue of the Classmate's power scheme (actually Intel's power saving scheme called SpeedStep). We have been programming with LabView; however, I see this as a Classmate DS/DB issue not a cRIO issue.

We would see it in wireless or tethered modes, and would see the watchdogs typically disappear when the Classmate was powered with the AC adaptor. If you see watchdog errors disappear with AC power I suggest you read more about it in this thread:
