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 kernel.org 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
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I was following the Linux Kernel in a Nutshell as guide but seems a bit outdated and brief.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.
You should use the ubuntu sources.
