[Bug 1871182] Re: [RTL810xE] No ethernet connection

[You-Sheng Yang]

@Ryan, those error messages are irrelevant here.

Could you try to:
1. remove 'realtek' from your /etc/modules temporarily
2. run `sudo update-initramfs -v -u` and attach the output messages
3. run `unmkinitramfs /boot/initrd.img-$(uname -r) some_temp_folder && find some_temp_folder -name realtek.ko` and check if realtek.ko is packed.
4. if it doesn't appear in the extracted folder, you may want to redo comment #4 to add it back after these experiments.

The result from my side is positive, but maybe for some reason
realtek.ko was not included automatically for you.
