Now, demidecode shows that the watchdog timer is present, but how would I know which driver does it need from the /etc/modprobe.d/blacklist-watchdog.conf file?

watchdog.conf
Code:
#ping			= 172.31.14.1
#ping			= 172.26.1.255
#interface		= eth0
#file			= /var/log/messages
#change			= 1407

# Uncomment to enable test. Setting one of these values to '0' disables it.
# These values will hopefully never reboot your machine during normal use
# (if your machine is really hung, the loadavg will go much higher than 25)
#max-load-1		= 2
#max-load-5		= 1
#max-load-15		= 1

# Note that this is the number of pages!
# To get the real size, check how large the pagesize is on your machine.
#min-memory		= 1

#repair-binary		= /usr/sbin/repair
#repair-timeout		= 
#test-binary		= 
#test-timeout		= 

watchdog-device	= /dev/watchdog

# Defaults compiled into the binary
#temperature-device	=
#max-temperature	= 120

# Defaults compiled into the binary
#admin			= root
#interval		= 1
#logtick                = 1
#log-dir		= /var/log/watchdog

# This greatly decreases the chance that watchdog won't be scheduled before
# your machine is really loaded
realtime		= yes
priority		= 1

# Check if syslogd is still running by enabling the following line
#pidfile		= /var/run/syslogd.pid
Code:
:~# watchdog --config-file /home/ravi/./watchdog.conf 
:~# grep watchdog /var/log/syslog
Aug  7 15:07:28 ravi-hrsl watchdog[8625]: starting daemon (5.11):

Aug  7 15:07:28 ravi-hrsl watchdog[8625]: cannot get watchdog identity (errno = 25 = 'Inappropriate ioctl for device')
This code does NOT restart the system:
Code:
# touch /forcefsck
# sync
# pkill -9 watchdog
# for n in $(seq 1 60); do echo $n; sleep 1; sync; done
What else info can I present here to help you to help me?

Thanks but that's talking about that "software" watchdog. I want a
driver for the hardware watchdog.
