Logging kernel message from the startup

[NoDataFound]

Hello,

I have seen on the screen a module which failed to load - something likle "nct6775" and [!!] on the right of the screen. I pretty sure that lmsensor module is failing and why - I've used sensors-detect and it found nct6775 (Nuvoton NCT5573D/NCT5577D/NCT6776F Super IO Sensors) which is probably not built into my modules.

But then again I don't see any error in the kernel log (dmesg, /var/log/dmesg, /var/log/messages).
Which is why I wondered the net in search of a solution to log those event so that I can investigate, but I can't find a proper way to do :

- This indicate some service on Debian : https://superuser.com/questions/176165/where-linux-places-the-messages-of-boot#176169 but I can't find any information on it, The bootlog does not exists (at list in eix after eix-sync)
- This date back from 2008 (https://forums.gentoo.org/viewtopic-t-409643-view-next.html) and it speak about that bootlog... which I can't find.

Is there a proper 2018-way of doing that ?

NoDataFound,

The rc-logger may capture that. Read and edit /etc/rc.conf.

You can try the stone age way too.
That's

Well, modprobe is a solution but it was more general (since I cached a glimpse of this error, modprobe is fine when you know which module is failing).
[edit] and my problem is because the module is not compiled

The modification of rc.conf worked fine:
