Hello Himanshu

This issue seems to be related to the actual card in my case.
I moved another QLogic QLE2562 into the same server and put it in another PCIE slot

This new one works :)

The other one still fails

I must be honest this had me going for days because 4.9.13 works fine :)

Anyway, next week I will see if I can get hold of you to chat about it in Boston because its a stange one

Thanks for your patience and assistance
