Question ALERT! /dev/disk/by-uuid/.... does not exist. Dr. opping to a shell!

Hello, I am new in Linux Kernel development and I have got stuck in my fisrt kernel compilation due to an error related to root fs detection at boot.

When I try to boot my kernel I got the error in the subject:

ALERT! /dev/disk/by-uuid/blah.blah. does not exist. Dr. opping to a shell!

By looking at dmesg I see a suspecting line:

scsi_transport_spi: disagrees about version of symbol module layout

The process I have followed to build my kernel is to download the sources from matching the kernel version installed on my running linux.

1-Copying the kernel config-2.6.31-14-generic from /boot and compiling
2-Copying initrd with copio adapting the directory names
3-Configuring grub

After the boot crash I can only see in /dev/disks a directory by-.path with an entry for pci-0000:00:07.1-scsi-1:0:0:0
But I am missing the partition device files.

I was following the Linux Kernel in a Nutshell as guide but seems a bit outdated and brief. So if you could reference a better guide would be very appreciated.

Thank you
