Thank you for noticing that difference.

This aligns with my not seeing any activity on the smbus with an oscilloscope during the i2cdetect process. What am I missing on why it is not communicating and/or finding my Lynx Point PCH as well as the devices connected to that smbus? >>> >>> As always, thank you, everyone. >> >> Next step might be to run lspci -nn and compare the output with the PCI IDs >> supported by your version of the i2c-i801 driver. > > And again, check the kernel log after loading the i2c-i801 driver.

I tested it last night; it fails to load on that system because of an ACPI conflict.
