Hi Grogster,
Can you determine if the watchdog really caused it -or- that it failed to kick in in a watchdog situation (and failed to revive the system).
Another thing I can think of is when the ARM is doing USB (which is infrequent and short..so.. "rare") while the watchdog kicks in (it is hardware, so independent of what software is doing) the USB stack is killed at an unknown state.
To be honest, I would not really be able to help you. Since I mostly run leading edge firmware, and only have few picomite systems that I turn off after use. I did not ever implement watchdog, they reboot every time I use them.
