i not sure the problem

You have an ethernet card that requires firmware to work. That's unusual; mostly it is wireless cards that create that sort of problem. The kernel is trying to load the firmware onto the card and failing.

So:
1) do you have that named file available in /lib/firmware? If not, you must copy it over from your host system.
2) Have you built your ethernet driver as a module or directly into the kernel? For cards that need to use firmware, the kernel's card driver should always be built as a module. That ensures that firmware files on the hard drive will be available when the network card is configured.

******
thank for answer in 1) but in 2) i don't know how to built ethernet driver as a module.

Go back into your kernel source tree and make sure you have a safety copy of your .config file somewhere else (most people keep theirs in /boot as config-4.18.3). Make mrproper, then copy the configuration file back as .config.

Make menuconfig. Go to Device drivers-->Network device support and find the driver for your card. If it is built in, it will have an asterisk * beside it. Change this to M for module. You can either type M or use the space bar to cycle through the possibilities. Then build and reinstall the kernel and its modules as in the book. You did it successfully once so you can do it again.

Note: when you do "make modules_install", you will be creating a new /lib/modules/4.18.3 directory, so you must first rename the existing one to something else, for example 4.18.3.old.

ok thank my friend and help me again last error please

That doesn't look like an error to me. That looks like a successful launch.

What do you mean, you can't enter anything in your prompt? What prompt? And why are you suddenly showing me your grub menu? You didn't have a grub problem up until now. Do try to think logically and don't expect me to do everything for you.

Press return, let grub boot the kernel, and in due course you will get a login prompt. Enter "root" and the root password you created in chapter 6. Then, once you are logged in, you can check your ethernet connection by pinging a suitable ip address. I suggest you try your router address first. If that works, try the Google dns server at 8.8.8.8.

Moin,

First of all, the missing firmware for the rtl8168 should be no problem. Having the same here, without any trouble with the card.
iirc, there are firmware packages available somewhere in the www, maybe at the debian site. But i did not yet recognize any difference in the networkdevice, regardless if the firmware is there or not.

Then i suspect, that something with your starting scripts is going wrong;
is it possible, that you mixed up instructions from the "normal" LFS and LFS-systemd during your build?

Hello,

Is it solved. I once meet an issue with rtl wifi driver. The version was Linux-4.16.18. Once the issue happened, my system never responded. I couldn't type anything. I think I read similar error report on Redhat community and it has already been fixed in later kernels.

Now I am using Linux-4.18.20 and it works fine.
