DKMS install failing on Debain 11, kernel 5.10.x

[noahbailey]

Hardware: NUC6CAYH OS: Debain Bullseye - Kernel 5.10.0-9-amd64

Problem: When I attempt the dkms-install, I'm getting errors back.

$ sudo make dkms-install
dkms add --force /home/noah/intel_nuc_led

Thanks all!!

This repo doesnt have the necessary patch for the kernel module to compile on anything using 5.6.0 or newer. You need to use a downstream fork for that patch for now.

[docop]

so is installing debian 10 will then make this work ?

[ju2wheels]

Try this downstream fork, it merges a bunch of the downstream forks and adds support for more NUC models and separates the driver from the userland controls: https://github.com/tvision-insights/intel_nuc_led . This fork should compile ok on pre 5.6.0 kernels and newer kernels (ive used it up to kernel 6.2.0)

I dont know if this current repo will work on Debian 10, depends what the kernel version is which I dont know off the top of my head.
