    Hi John,

    Yes I have some questions. I pulled out one of the two Arria 10 GX PAC to try to fix the driver. I tried to reinstall the development kit, but it seems still not installed successfully.

    After I reinstalled the development software, "lspci" logs shows the PAC device 09c5 could be found:

    However, "lsmod | grep fpga" logs still not full:

    Before I started using two PAC cards, the driver was perfectly usable with my code.

    Question:

    What's wrong the the driver now? What should I do to fix the driver at first? I want to check whether I miss some operations before I reinstalled the driver.

    If there are any useful documents could be provided to show me the correct steps to let multiple PAC cards running was really appreciated.

    Thanks. Best wishes.
