Loading with /etc/modules-load.d/nct6687.conf doesn't work #76

Arch Linux user here. I do sudo sh -c 'echo "nct6687" >> /etc/modules-load.d/nct6687.conf' as suggested, but at loading time I get this message from driver: kernel: nct6687: loading out-of-tree module taints kernel. kernel: nct6687: module verification failed: signature and/or required key missing - tainting kernel kernel: nct6687: EC base I/O port unconfigured systemd-modules-load[322]: Failed to insert module 'nct6687': No such device kernel: nct6683: Found NCT6687D or compatible chip at 0x4e:0xa20 And module doesn't work until I do sudo modprobe nct6687 Once upon a time (a couple of boots) it worked, but no more.

What does this error means? Why it works with manual probing?

I think that you need to rebuild the module after upgrading dev tools

It is installed with DKMS, so rebuilded regularly. And it is Arch, so there's nothing to upgrade more than it is.

Sometimes the build-essential package is not up to date. as the the message say: the version of the buildin kernel is not the same a thé build-essential package to build kernel modules.

often i have the same problem on ubuntu.

If you talk about 'module tainting kernel', it's not definitely a reason. Those times when module was loaded at boot time, this message appeared too, and gurus at Arch message board tells me that it's just a warning. But next message, 'EC base I/O port unconfigured', is the indicator of some floating problem. But I have no enough knowledge in kernel programming to understand what's happening at that time and what can I do (or how I can configure boot process) to resolve this situation.
