[A non-zero value is the number of seconds before rebooting. zero means don't reboot]

Can you set up a serial console for this system?  Seeing the kernel
log leading up to the machine checks might also give some clues (e.g.
perhaps rawtherapee is running the system out of memory right before
the crash).
