For anyone experiencing periodic system watchdog errors please see my posting here:

I have found that our problem with multiple system watchdog errors per minute was being caused by some issue with Intel's SpeedStep power saving scheme (on the Atom processor of the Classmate). By going into BIOS and disabling the SpeedStep and C-State options I was able to elimate our errors.
We do still have a system watchdog error when transitioning from Autonomous Enable to Disabled and TeleOp Enabled to Disable... more investigating to do.
