Comment 13 for bug 576602

Same problem here with Ubuntu 13.4

To solve the problem I launch pwmconfig, and search those lines (may differ on your computer) :

____________________________________________
[…]
Found the following devices:
   hwmon0/device is it8721
   hwmon1/device is k10temp
   hwmon2/device is fam15h_power
[…]
____________________________________________

Then I write (as root) a config file named /etc/modprobe.d/fancontrol.conf with this content (modules names can differ a little to names given by pwmconfig, use lsmod to find them) :

____________________________________________
softdep fam15h_power pre:k10temp
softdep k10temp pre: it87
____________________________________________

Then I rebuild initramfs

____________________________________________
root@ubuntu # update-initramfs -k all -u
[…]

At boot time, fam15h_power module can't be loaded before k10temp module, and k10temp module can't be loaded before it87 module. It forces module load order.
