Need help setting up Hardware Watchdog in Debian Jessie
(Sorry my previous message did not create a new thread.)
I have been searching google and trying everything I can think of to get
hardware watchdog setup but the server keeps rebooting after 5 minutes.
What am I doing wrong, and what do I need to do to get hardware watchdog
working in Debian Jessie. Please help.
List of IPMI BMC Info:

SMBIOS 2.7 present.

# apt-get install openipmi
# apt-get install ipmitool
While installing ipmitools there was an error message "Job for
ipmievd.service failed...." because /dev/ipmi0 was not created yet. I
rebooted and reinstalled ipmitool.
# apt-get install --reinstall ipmitool
# lsmod | grep ipmi
# dmesg | grep ipmi

Is there a conflict with there being duplicate interfaces, and should
one be used in place of the other and if so how?
The boot time startup screen listed
watchdog: iTCO_wdt: cannot register miscdev on minor=130 (err=-16).
watchdog: iTCO_wdt: a legacy watchdog module is probably present.
To solve this issue I blacklisted the following modules so they would
not load into the kernel.
Also setting the following option in '/etc/default/grub' before running
While I was trouble shooting, I also blacklisted
And I used 'lsmod' to verified that none of the blacklisted modules were
loaded into the kernel.
Then I install the watchdog service:
# apt-get install watchdog
I edited the watchdog daemon config file:
# nano /etc/watchdog.conf
# ipmitool mc watchdog get

While I can manually start the 'watchdog.service' and 'ipmievd.service',
these serviced do not start automatically at boot time.
'systemctl enable <service name>' does not enable either service with
the following output listed:
Synchronizing state for watchdog.service with sysvinit using update-rc.d...
Executing /usr/sbin/update-rc.d watchdog defaults
Executing /usr/sbin/update-rc.d watchdog enable
The unit files have no [Install] section. they are not ment to be
enabled using systemctl.
How should I start the services automatically at boot time?
The motherboard has a jumper (JI2C1) for the 'I2C Bus to PCI-Exp.
Slots'. The jumper is currenly disabled. Does this jumper need to be
enabled as the output for 'dmidecode --type 38' lists an 'I2C Slave
Address: 0x00' ?
I read about setting the following parameters, but there was no
Am I supposed to set these parameters and if so where?
Is there supposed to be an ipmi.service? If so how does it get installed?
