pwmconfig gets outdated on every reboot

ubuntu version- 13.04
cpu- amd phenom II x6 1055t

fancontrol version--

fancontrol:
  Installed: 1:3.3.2-2ubuntu1
  Candidate: 1:3.3.2-2ubuntu1
  Version table:
 *** 1:3.3.2-2ubuntu1 0
        500 http://in.archive.ubuntu.com/ubuntu/ raring/universe amd64 Packages
        100 /var/lib/dpkg/status

every time i reboot the system and run
sudo fancontrol
i always get the error device configuration is outdated ,run pwmconfig again

Usually the problem is the devices listed as hwmon0/* have changed to hwmon1/* or vice versa.

Fancontrol is not started at boot as the pwmconfig is wrong anyways, so i have to run pwmconfig and save the changes.

Once this is done fancontrol runs fine.
