It seems that you have a watchdog device (probably provided by the
motherboard of your pc/server) that is not currently usable by wdmd.

The temporary workaround to get your system to work is to modprobe
the softdog kernel module and restart wdmd:

 # modprobe softdog
 # service wdmd restart

Depending on the distribution you're using there are different ways
to automatically load the module at boot, for example on fedora you
can use:

http://www.freedesktop.org/software/systemd/man/modules-load.d.html

and for centos/rhel 6 you can look at the content of:

/etc/sysconfig/modules

for an example of how to do the same (e.g. kvm.modules).

That said, in order to get your specific watchdog device to work
properly I'd need some additional information. Can you provide me
the output of these two commands?

 # lspci -vvv
 # lsmod

Thanks,
