      Hi,
      we are seeing problems with the T520 on Supermicro A2SDi-4C-HLN4F.
      The card is detected in 1 of 4 bootups.

      Bios updated on newest version.

      Any suggestions?

        Like the driver doesn't attach or it isn't reported by pciconf?

        Does it show in the BIOS at all in either situation?

        Steve

          Probably found the issue:

          There is a bios setting which changes the PCIe from x2 to x4 (while disabling SATA ports).

          Advanced >> Chipset Configuration >> South Bridge Configuration >>Flexible I/O Selection (default is [PCIe x 2/Mini SAS/SATA(1:0)])

          Changing this to PCIe x4 seems to resolve the issue.
