RedHat: VFS: Cannot open root device

I have RedHat 9, kernel 2.4.20-31.9. I have rebuild the kernel to increase the VMALLOCRESERVE to 256MB. Here are the steps I have followed:

make mrproper cp config-2.4.20-31.1usr-src-linux-.config make oldconfig make dep make bzImage make modules make modulesinstall make install

Now I have a new kernel 2.4.20-31.9custom. When I boot this kernel I get the following error:

cdrecord k3b audio cd elapsed time problem
Hi, When I copy an audio cd using cdrecord or k3b, it seems to go without problems. However, it won't play properly in most cd players. The first track...

VFS: Cannot open root device "LABEL=-" or 00:00 Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on 00:00

I use grub as bootloader. Here is my grub.conf file:

# grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have aboot parbreastion. This means that # all kernel and initrd paths are relative toboot-, eg. # root (hd0,0) # kernelvmlinuz-version ro root=-dev-hda3 # initrdinitrd-version.img #boot=-dev-hda default=0 timeout=10 splashimage=(hd0,0)-grub-splash.xpm.gz breastle Red Hat Linux (2.4.20-31.9custom) root (hd0,0) kernelvmlinuz-2.4.20-31.9custom ro root=LABEL=hdd=ide-scsi initrdinitrd-2.4.20-31.9custom.img breastle Red Hat Linux (2.4.20-31.9) root (hd0,0) kernelvmlinuz-2.4.20-31.9 ro root=LABEL=hdd=ide-scsi initrdinitrd-2.4.20-31.9.img

If I change the following line like this (replace root=LABEL=with root=-dev-hdc3): kernelvmlinuz-2.4.20-31.9custom ro root=-dev-hdc3 hdd=ide-scsi

It works! Why the boot option "root=LABEL=-" works for my kernel 2.4.20-31.9 and not for my kernel 2.4.20-31.9custom?

Thank you.
