I started bisecting this, cannot believe others have not bumped into this on 4.10. This is a generic QLE2562 and firmware is loaded by the driver so wondering why I am seeing this and other are not. There is nothing special with the PCIE bus on this DL380G8. Anyway during the bisect I got to a point where in the 4.10 commits I still saw the "BAR 3" message but the probe worked.
