=== lm_sensors: sensors-detect finds a sensor but cannot load module ===

After installing lm_sensors and running sensors-detect, the following happens:

{{highlight|lang=terminal|code=
# sensors-detect
*omitting first part of sensors-detect output*

Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Driver `w83627hf':
* ISA bus, address 0x290
Chip `Winbond W83637HF/HG Super IO Sensors' (confidence: 9)

Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no):
Starting lm_sensors: loading module w83627hf No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.
[FAILED]

Unloading i2c-dev... OK
}}

It is obvious that a sensor was found, but the module is not being loaded. Check dmesg to see if there is an ACPI conflict:

{{highlight|lang=terminal|code=
# dmesg {{!}} tail
w83627hf: Found W83637HF chip at 0x290
ACPI: I/O resource w83627hf [0x295-0x296] conflicts with ACPI region IP__ [0x295-0x296]

To resolve this issue, add {{code|1=acpi_enforce_resources=lax}} to the boot parameters:

{{highlight|lang=text|code=
