As I noted in bug 524956, this regression effects more than just fans and temperature sensors. On my machine, it renders the Bluetooth and WiFi kill switches inoperable (resulting in the built-in bluetooth to be permanently off and WiFi to be permanently on). Also, the laptop lid state is not detected.
I believe this bug is a duplicate of Bug #524956. The upstream bug is https:/ /bugzilla. kernel. org/show_ bug.cgi? id=14667
