My kernel version is v4.4, and I have built drivers/staging/dgnc/dgnc.ko.
I change to *dir*/drivers/staging/dgnc and do like this:

    sudo insmod ./dgnc.ko
    sudo lsmod | grep dgnc
    sudo rmmod ./dgnc
    sudo insmod ./dgnc.ko

After I re-insmod the dgnc module, my laptop is breakdown.

My OS is debian 8.0. Is there a bug in dgnc.ko or something wrong with my
OS or kernel. If there is a bug, How can I find it?
