+          This option controls the default timeout (in seconds) used
+          to determine when a task has become non-responsive and should
+          be considered hung.
+
+          It can be adjusted at runtime via the kernel.hung_task_timeout
+          sysctl or by writing a value to /proc/sys/kernel/hung_task_timeout.
+
+          A timeout of 0 disables the check.  The default is two minutes.
+          Keeping the default should be fine in most cases.
