I think it makes sense on production systems as well, you can think of the
NMI-watchdog as a 'more reliable watchdog timer'. While normal watchdog
timers can be stopped by buggy kernel code, NMI timers cannot. I plan to
add some trivial hooks to fold this new functionality transparently into
softdog.c, so it will work out of box with existing watchdog daemons, the
only difference that on SMP the thing will be a bit more reliable. This is
why the config option is amongst Char Devices/Watchdogs.
of course a real watchdog card can do even more.
