This is a PCIe LAN-on-motherboard. My goal is to understand whether this is a problem in the atl1 driver, or a problem on the motherboard. If it's the former, obviously I want to fix it. If it's the latter, then I want to disable MSI in the driver when we discover we're running on this motherboard. Thanks again for taking time to look at this. Any advice or hints you provide will be greatly appreciated.
