Hi!

I have installed LFS for the first time and the boot hangs after "md: ...autorun Done". I found only one topic related to this here: https://www.linuxquestions.org/quest...n-done-203250/

I am hesitant to recompile the kernel without RAID support, but should I do it or are there other options / troubleshooting steps I should take?

Any help would be appreciated!

"md: ...autorun Done" is not an error, so unlikely to be the cause of your problem. Look at earlier lines for the error.

May be missing drivers that need to be compiled into the kernel for a successful boot.

Thanks for the replies! I get no other errors. Just information about what devices are found such as hard drives, USB-devices, etc. The screen just freezes and the computer can only be turned off via pulling the power plug.

I will take a look at the Kernel once more. I did all the configurations that the LFS book recommended me to do. I will recheck them. Are there any others I should check? I noted the BLFS book has a part about mesa drivers, so maybe I will do that as I have an AMD CPU.

Specs:
Gigabyte Technology Co., Ltd. X670 GAMING X AX
AMD Ryzen 7 7700X
AMD Radeon™ RX 6800 XT
RAM 32.0*GiB DDR5

On what device is your root filesystem? Can you see it get mounted in the log?

You didn't say what version of LFS you are building, sysvinit or systemd based, or what host you are using. If recent sysvinit based (udev extracted from systemd instead of separate eudev package) don't forget this line in your fstab:
- believe it or not, that can cause the issue you are describing. Also, make sure you have the required radeon GPU firmware in /usr/lib/firmware. Look in dmesg output of the host for the exact firmware being used or just install all of the radeon firmware.

Hi! Thanks for the replies. I haven't had much time to work on this, but perhaps in the weekend. This is my fstab, which should be correct as I copy & pasted it from the book. I am building the sysvinit and I followed all the steps in the book.

I did not install any firmware. I found this article from BLFS, https://www.linuxfromscratch.org/blf.../firmware.html, should I follow it as well?

I failed to find anything in the logs by checking /var/log, all is empty. I can try booting it later again and see if I can spot anything sus.

Moin,

This might be a good idea. Maybe pretty much the same happened to me here:

Hi! Thanks for all the responses. I installed the firmware and I was able to get past the original problem. I tried booting LFS and my PC was no longer freezing on the same line. Instead, I got a nice kernel panic about "unable to mount root fs", which is a better situation as I now have some output. I need to do some investigating on what causes this error. I did notice that the output (see image below) shows some problems on the hard-drive I have LFS installed on (/dev/sdb) as it lists only one partition instead of the three. I posted my fstab above and I did notice that my swap partition was listed as /dev/sb2 instead of /dev/sdb2, which I fixed. This didn't fix the kernel panic, but good progress anyways. I did check the kernel configuration that ext4 was ticker on with *. Any tips regarding this new issue is also appreciated :-) Thank you!

Here is an image I took of the kernel panic:

Moin,

This sounds weird. What does tell, if your're running it from the Hostsystem (the one you used to build LFS)?

Cheers,
WK

/dev/sdb doesn't show any partitions. If it isn't a missing driver problem in the kernel, the drive order may be changing when a usb drive is plugged in. To work around this use lsblk -f to find the uuids of the lfs install and change the fstab to use uuids something similar to this
If this is a uefi system did you look at this: https://www.linuxfromscratch.org/blf...ml#uefi-kernel

Hi all and thank you all for your continuous support, great community! I have gotten the installation working now. I tweaked some of the kernel settings and messed about with my fstab -file. I also installed initramfs. It is unclear to me which one of these worked though �� the important thing is that I now have a running system and I can continue inspecting and learning it.

To recap, overall I had to do the following things:
- Went through the kernel configuration again and compiled it
- Installed firmware for my GPU and CPU
- Triple checked my /etc/fstab file
- Installed initramfs
