Since version 3.2.2 the module w83627ehf can no longer be loaded. Relevant dmesg output:

[ 169.279442] w83627ehf: Found NCT6776F chip at 0x290
[ 169.279506] ACPI: resource w83627ehf [io 0x0295-0x0296] conflicts with ACPI region HWRE [io 0x290-0x299]
[ 169.279511] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver

(I'll try to figure out later and add more information; for now just wanted to let you know that there might be a problem)

This is not a bug.

I reported the problem (not knowing what caused it) and got the following explanation from Jean Delvare:

"That was indeed a bug... in 3.2. Kernels between 2.6.39 and 3.2
(inclusive) lack the ACPI resource conflict check, it was accidentally
disabled. And this is fixed in 3.3.

See
http://www.lm-sensors.org/wiki/FAQ/Chapter3#Mysensorshavestoppedworkinginkernel2.6.31
for details."

Pierre , Tom is this fixed in 3.4.x? nothing mentioned on the wiki anymore.

As far as I understand the warning is not a bug. It simply means that you should not attempt to load the module as it conflicts with the acpi one.
