It is not the best watchdog, but it will print the register state for each core when things get stuck. Occasionally that is enough to see where the problem is.Thanks. As our logging has only limited buffer size, I'd be happy about an variant of the patch which doesn't reboot but just let the machine hang after the third occurence. Any chances for it?
You could just sit in a loop kicking the watchdog timer after you get to the NMI handler. That should prevent a reset, but still print the machine state.
