unable to load firmware patch rtl_nic/rtlXXXX

[NeoSeppl]

Hi,

experiencing warnings for my two Realtek USB NICs while booting my Raspberry Pi 4 Model B Rev 1.1

Kernel is Linux underworld 6.12.6-1-rpi #1 SMP PREEMPT Fri Dec 20 07:11:12 MST 2024 aarch64 GNU/Linux

Errors in Kernel log:

How can I get rid of those?

I did some investigation by myself:
- Firmware files are present and located under /usr/lib/firmware/rtl_nic/
- Firmware files are not included in the mkinitcpio image
- fwupd is not installed (do I need it?)

Appreciate some hints / ideas to solve. Thx.

Hard to say, but from my understanding the kernel usually looks at /lib/firmware/ not /usr/lib/firmware/

Yes, that's what I checked as well.

[code]lrwxrwxrwx 1 root root 7 26. Nov 01:15 lib -> usr/lib[/code]

/lib is a symlink to /usr/lib - does the kernel follow symlinks?
