Core 16 Fresh Install Broadcom kernel taints

General Help
#1

Everything works fine so far - just poking around in my fresh install of Core 16..... what's this about?? I selected 3rd party drivers on install, since I have Broadcom wifi :frowning_face: not familiar with kernel taints.

$ dmesg | grep wl
17.076301] wl: loading out-of-tree module taints kernel.
[ 17.076311] wl: module license 'MIXED/Proprietary' taints kernel.

Have you checked your firmware?

sudo service fwupd start

sudo fwupdmgr refresh

sudo fwupdmgr update

#3

Fresh install with updates installed during install

#4

Again, everything works fine on wifi, just wondering about the errors. :nerd_face:

#5

It can happen if using an unsigned kernel or unsigned modules with a signed kernel.
The signed kernel may be "tainted" by the unsigned one - it is a security warning that if anything is unstable or broken in an unsigned module, this can affect stable and non-broken elements of the signed module or kernel.

Now I know. I learned something today, so I can have a beer and go to bed!
Thanks @Aravisian, perfect!
