It seems your root (/) partition lies on a logical volume, and you've not
compiled support for the LV in kernel or LV node was not created by then, you
need an initial ramdisk image which will scan disk for LVM volumes, create
their appropriate nodes, and pass control to init on /.
Not sure about how Fedora 8 manages initrd creation, but you can figure out
that by executing:
#v+
% rpm -q --scripts postinst kernel
postinstall scriptlet (using /bin/sh):
if [ `uname -i` == "x86_64" -o `uname -i` == "i386" ]; then
if [ -f /etc/sysconfig/kernel ]; then
/bin/sed -i -e 's/^DEFAULTKERNEL=kernel-smp$/DEFAULTKERNEL=kernel/'
/etc/sysconfig/kernel || exit $?
fi
fi
/sbin/new-kernel-pkg --package kernel --mkinitrd --depmod --install
2.6.18-53.1.4.el5 || exit $?
if [ -x /sbin/weak-modules ]
then
/sbin/weak-modules --add-kernel 2.6.18-53.1.4.el5 || exit $?
fi
[...]
#v-
The 'postinstall' section is what you've to execute for your kernel, the
'new-kernel-pkg' statement to generate an initrd image, after that boot your
new kernel with initrd.
