Hi,

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

What output, if any, did this generate?

sudo lsmod | grep dgnc

Again, what messages?

sudo rmmod ./dgnc

Again, what happened?

sudo insmod ./dgnc.ko

And here?

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

What does "breakdown" mean? Did it hang entirely? Did you get a message in your dmesg output and/or on the console? Other?

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?

Start by providing enough info to see if there's a bug.
