When loading the i801 i2c bus driver on an i5-46xx CPU, and this chipset http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/8-series-chipset-pch-datasheet.pdf I see the following warning: i801_smbus 0000:00:1f.3: PCI INT C -> GSI 18 (level, low) -> IRQ 18 ACPI: resource 0000:00:1f.3 [io 0xefa0-0xefbf] conflicts with ACPI region SMBI [io 0xefa0-0xefaf] ACPI: This conflict may cause random problems and system instability ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver It seems like the BIOS/ACPI defines a region, SMBI, which is defined for the SMBus to use, but there is no ACPI driver available for the SMBus (at least AFAICT). I'm using "acpi_enforce_resources=lax" as a kernel parameter to work around the issue but was wondering if there was a more robust fix planned for this problem? If not -- anyone want to point me in the right direction of a fix?
