Boot problem after compiling the kernel

[Jorge Castelao]

I have compiled the kernel 2.4.22-1.2129.nptl for adding ntfs support.
Everything was OK, and the following lines werw added to the grub.conf:


title Fedora Core (2.4.22-1.2129.nptlcustom)
	root (hd1,0)
	kernel /vmlinuz-2.4.22-1.2129.nptlcustom ro root=LABEL=/ hdd=ide-scsi
rhgb
	initrd /initrd-2.4.22-1.2129.nptlcustom.img

The problem is that when booting with the new kernel, I have the error
message:

VFS: Cannot open root device "LABEL=/" or 00:00

The problem is solved changing (in the grub.conf) 'root=LABEL=/' by
'root="/dev/hdb2"' (is where my / is), but I would like to know the
reason and why this problem doesn't appear with the old kernel.

Thanks in advance.
