Dmesg acpi warning message - question please
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)

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
