Short term, you can disable the hardware watchdog in kernel config. That should temporarily fix your problem, and if it does not . . . bigger mystery.
Long term, it would be good to figure out what is triggering the watchdog. strace on the watchdog PID will not work - I tested this myself. The only one thing I can think of off hand is perhaps modifying the watchdog module to output a debug message before rebooting the system. As to which process triggered a shutdown, and why. If possible . . . Will research more tomorrow it is very late ( actually early ) here.
