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?
No output. I use *dmesg* to find more information: [ 572.915977] dgnc: module is from the staging directory, the quality is unknown, you have been warned.
sudo lsmod | grep dgnc
Again, what messages?
Output: dgnc 65536 0
sudo rmmod ./dgnc
Again, what happened?
No output. After *dmesg*, no more info in the ring buffer.
sudo insmod ./dgnc.ko
And here?
No output.
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?
The GUI stop work and any key in my laptop is not work. The *Caps Lock lamp* in the keyboard is flashing.
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.
