[Solved] Problem booting custom kernel

Hello folks,

I tried to install a custom kernel on my archlinux 64-bit, following this wiki page: https://wiki.archlinux.org/index.php/Ke … ual_Method

I didn't had any problems, I got all three files in my /boot and also added the entry to the /boot/grub/menu.lst. But when I try to boot, I get an error like this "ramfs /dev/sda1 not found".
I have no idea where I failed. At least the kernel I use has default settings, and I didn't change anything on it yet.

Here is my /boot:

[tectu@Cosinus ~]$ ls -l /boot
total 32064
drwxr-xr-x 2 root root     4096 Jan 23 09:25 grub
-rw-r--r-- 1 root root  1656841 Jan 23 09:21 initramfs-customkernel.img
-rw-r--r-- 1 root root 10933394 Jan 20 10:37 initramfs-linux-fallback.img
-rw-r--r-- 1 root root  2550718 Jan 20 10:37 initramfs-linux.img
-rw-r--r-- 1 root root  2412590 Jan 20 11:31 System.map
-rw-r--r-- 1 root root  2412590 Jan 20 12:03 System.map-customkernel
-rw-r--r-- 1 root root  4834064 Jan 20 11:31 vmlinuz
-rw-r--r-- 1 root root  4834064 Jan 20 11:41 vmlinuz-customkernel
-rw-r--r-- 1 root root  3171280 Jan 13 06:53 vmlinuz-linux
[tectu@Cosinus ~]$ 

And here is (a part) of my /boot/grub/menu.lst

# (0) Arch Linux
title  Arch
root   (hd0,0)
kernel /boot/vmlinuz-linux root=/dev/sda1 ro
initrd /boot/initramfs-linux.img

title  Arch custom
root   (hd0,0)
kernel /boot/vmlinuz-customkernel root=/dev/sda1 ro
initrd /boot/initramfs-customkernel.img

# (1) Arch Linux
title  Arch Fallback
root   (hd0,0)
kernel /boot/vmlinuz-linux root=/dev/sda1 ro
initrd /boot/initramfs-linux-fallback.img

Does anyone have an idea, what i am doing wrong?

Do you need any additional Informations?

Thank you

Re: [Solved] Problem booting custom kernel

Solved... I missed to enable 'devtmpfs' while i was configuring the kernel.
