8 If you say Y here (and to one of the following options) and create a
9 character special file /dev/watchdog with major number 10 and minor
10 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
11 subsequently opening the file and then failing to write to it for
12 longer than 1 minute will result in rebooting the machine. This

16 reboot the machine) and a driver for hardware watchdog boards, which
17 are more robust and can also keep track of the temperature inside

21 The watchdog is usually used together with the watchdog daemon
22 which is available from
23 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
24 also monitor NFS connections and can reboot the machine when the process
25 table is full.

42 The default watchdog behaviour (which you get if you say N here) is
43 to stop the timer if the process managing it closes the file
44 /dev/watchdog. It's always remotely possible that this process might
45 get killed. If you say Y here, the watchdog cannot be stopped once

676 watchdog timer that will reboot the machine after its second
677 expiration. The expiration time can be configured with the
678 "heartbeat" parameter.
679
680 On some motherboards the driver may fail to reset the chipset's
681 NO_REBOOT flag which prevents the watchdog from rebooting the
682 machine. If this is the case you will get a kernel message like
683 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

702 This driver can be used with the watchdog timer found on some
703 single board computers, namely the 6010 PII based computer.
704 It may well work with other cards. It reads port 0x443 to enable
705 and re-set the watchdog timer, and reads port 0x45 to disable
706 the watchdog. If you have a card that behave in similar ways,
707 you can probably make this driver work with your card as well.

1140 to have watchdog support enabled, say Y, otherwise say N.
1141
1142 As a side note, saying Y here will automatically boost HZ to 1000
1143 so that the timer has a chance to clear the overflow counter. On
1144 slower systems (such as the SH-2 and SH-3) this will likely yield
1145 some performance issues. As such, the WDT should be avoided here
