I am not sure but most probably I did not have ext3 support at all. The most confusing part is that when I changed the line to root=/dev/hda2 from root=LABEL=/ it works fine !!! Can it be related to ext3 or is it a grub issue ? The problem is that I am right now trying on a standalone machine with the final goal to compile the kernel on a VM. And on the VM changing to /dev/hda2 or /dev/sda2 (virtual device) does not work.
I hope you understand the problem.
The /dev/hda2 indicates that the root filesystem is on an IDE drive, /dev/sda2 says it's on a SCSI drive. By using "root=LABEL=/", you bypass a device specification and depend on filesystem labels (you let grub go look at the labels and use the first one that is labeled "/").
Filesystem labels are dangerous if you turn on the IDE drive again, as there are likely two filesystems with the "/" label (one on the IDE, one on the SCSI). In that case, it's entirely possible to boot the WRONG version of the OS. I prefer device names to make it absolutely clear which drive and partition I want.

Hi,
I dont know if I have asked this question before but why I am always getting the error :
"Unable to mount on 0,0 cannot find root=label=/" ?
The complilation steps are ...
make dep
make bzImage
make modules
make modules_install
make install
Is it because I am compiling a kernel (2.4.21) without ext3 support on an ext3 FS ? but I have also tried compiling the an ext3 kernel and I got the same error.
can some one tell me whats going on ?
If the root filesystem is ext3 you must either:
a) have the ext3 filesystem built into the new kernel, or
b) build the ext3 filesystem as a module and include it in the initrd image for the new kernel
