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.

[ 7.208492] qla2xxx [0000:27:00.0]-001b: : BAR 3 not enabled.
see this above but probe did not fail

I marked that still as bad and am continuing, I have 9 builds to go.
Thanks
