Which OS/kernel are you using?
Can you post the output of dmesg?

Can you also post the dmesg output you get when loading the kernel module? Normally, it should be something like this:

I cannot reproduce the problem. I just tested it with a 4.4.0 kernel and it's working fine for me. Maybe you are using some non-default kernel option, or there is an incompatibility with some other kernel module. I would suggest booting from a flash drive with Ubuntu 18.04 and trying again in that environment.
