[SOLVED] Booting without initramfs failed

Hi,

I tried to improve boot speed and get a bit more familiar with the linux kernel so i tried to compile my own kernel without an initramfs

Thats how it looks like 

efibootmgr -c -d /dev/sda -p 1 -l \vmlinuz-linux-custom -L  Arch_Linux_Custom -u "rootfstype=xfs rw elevator=noop quiet" 

I got the build in kernel commandline with

root=/dev/sda2

to generate the kernel i used localmodconfig and changed some things with nconfig (no initramfs support and enabled all efi features)

when i tried to boot i got an error

vfs unable to mount root fs on unknown-block

Do you have any idea what i am doing wrong if you need more information just tell me

Thanks for the help

Bene

Re: [SOLVED] Booting without initramfs failed

Did you enable the xfs configuration as a built-in rather than a module?

I guess i did not do it, i searched on the internet and find nothing, how can i do it?
I also searched in Nconfig but so far i found nothing.

Is this the series of error messages you are getting?
