Hi,

I am trying to install a new kernel (2.6.19-1), with the web100 patch
(2.5.13), on Redhat Enterprise linux-2.6.9-5.ELsmp

I patch compile and build the kernel successfully, and I move the image
to the /boot directory.

When I try to boot it (with grub), I get the following Kernel Panic
message:

VFS: Cannot open root device "/dev/VolGroup_ID_24096/LogVol1" or
unknown-block(0,0)
Please append a correct "root" boot option
Kernel Panic - not syncing: VFS: unable to mount root fs or
unknown-block(0,0)

My default grub.conf file is:
default=0
timeout=5
splashimage=(hd0,2)/grub/splash.xpm.gz
hiddenmenu
title Red Hat Enterprise Linux AS (2.6.9-5.ELsmp)
        root (hd0,2)
        kernel /vmlinuz-2.6.9-5.ELsmp ro
root=/dev/VolGroup_ID_24096/LogVol1 rhgb quiet iommu=soft numa=off
        initrd /initrd-2.6.9-5.ELsmp.img
title Red Hat Enterprise Linux AS-up (2.6.9-5.EL)
        root (hd0,2)
        kernel /vmlinuz-2.6.9-5.EL ro
root=/dev/VolGroup_ID_24096/LogVol1 rhgb quiet iommu=soft numa=off
        initrd /initrd-2.6.9-5.EL.img

What can I do to solve that Kernel Panic, and get the new kernel to boot
properly?

Thanks!

Nathalie~
