Another Wheezy AMD64 RC1 on Gigabyte GA-G41M-Combo Rev. 2.0 issue is inadequate hardware sensors monitoring after installation.
Solution:
1) Detect available sensors by running
#/usr/sbin/sensors-detect
and letting it to add required lines to "/etc/modules".
2) Restart kmode:
#/etc/init.d/kmod start
3) You may wish to configure fan smart controls with "pwmconfig" if you do know what you are doing.
Wrong; needs some additional research.
