I'm trying to get a kernel module to load at boot.

If I run insmod /path/to/module.ko, it works fine. But this has to be repeated every time I reboot.

If I run modprobe /path/to/module.ko, it can't find the module. I know modprobe uses a configuration file, but I can't get it to load the module even after adding /path/to/module.ko to /etc/modules.

What is the proper configuration?

You can make a symbolic link of your module to the standard path, so depmod will see it and you'll be able load it as any other module.

sudo ln -s /path/to/module.ko /lib/modules/`uname -r`
sudo depmod -a
sudo modprobe module

If you add the module name to /etc/modules it will be loaded any time you boot.

Anyway I think that the proper configuration is to copy the module to the standard paths.
