    Some days ago I had same issue. My problem was very easy. Of course I
    already known it.
    I had another problem too. The smartctl is show me the next error what
    is growing up and up.
    199 UDMA_CRC_Error_Count
    Anyway the solution is very easy. I have two PCIe slot and I tried the
    another slot and that's it.
    Please write it back if it works for you. May be the FW downgrade is
    good idea.
    ps
    1 PCIe 1x16 (x16, PCIe 3.0)
    2 PCIe  1x16 (x4, PCIe 2.0)
    HBA FW is 20.
