Subject: Supermicro AOC-SLG3-2M2 dual M.2 card only identifies one drive

I picked up one of these and two intel 760p M.2 drives for use with a 
Supermicro X10SRA-F motherboard under 11.2-RELEASE-p3. The system only 
identifies drive that is mounted in the top slot. I believe this pci-e 
x8 card mostly just wires the (m-key) M.2 connectors pins to the pci 
slot pins. It looks like the top drive goes to the first 4 pci-e lanes 
and the bottom slot the next 4 pci-e lanes.

I suspect the driver is not even looking for the nvme that is connected 
to the second set of lanes. Can anyone tell me what it takes to support 
this configuration?
