Dmesg acpi warning message - question please

[Nick Warne]

Dear Devs,

Please could anybody explain what this message means in dmesg (and syslog) when I reboot my amdx86_64 machine:

i2c i2c-3: nForce2 SMBus adapter at 0x1c00
i2c i2c-4: nForce2 SMBus adapter at 0x1c40
it87: Found IT8712F chip at 0x290, revision 8
ACPI Warning: 0x0000000000000295-0x0000000000000296 SystemIO conflicts with Region \IP__ 1 (20130117/utaddress-251)
ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver

Please cc: me, as I am not subscribed.

Kind Regards,

Nick

Because it87 driver try to use io resource which
is used in the ACPI table. The it87 driver will not be
loaded successfully in this case.

Thank you - I just rebuilt kernel without it87 sensor driver and logs are clean, and lm-sensors/sensors work OK.

So basically, even though I have that chip, I should just let acpi do it's stuff?  I think that is what confused me.

Thanks,

Nick
