There's a lot going on in this patch. Could it possibly be split up a bit, e.g., first tease apart aer_err_info.status/.mask into .cor_status/mask and .uncor_status/mask, then add .uncor_severity, then add the device_status bit separately? If it could be split up, I think the ANFE case would be easier to see. Thanks a lot for working on this area! Bjorn
