Default value is set when compiling the kernel. If it is set
to "Y", then there is no way of disabling the watchdog once
it has been started.
+ kdumptimeout Minimum timeout in seconds to apply upon receipt of an NMI
+ before calling panic. (-1) disables the watchdog. When value
+ is > 0, the timer is reprogrammed with the greater of
+ value or current timeout value.
NOTE: More information about watchdog drivers in general, including the ioctl
