You said initrd lines were erased in grub.conf and the initrd* files
in /boot/grub were renamed. That's weird! I assume you have already
tried editing grub.conf to adapt it to the renamed initrd files, and since
you didn't say so, I assume that vmlinuz-2.6.18-348.18.1.el5 was not
renamed. If I'm mistaken, grub.conf should be edited accordingly, or the
files should be renamed back so as to be consistent with grub.conf.
I've no experience with a problem like yours, so I'll just guess that
something interfered with installation of the kernel rpm at an especially
bad step in the process. Check with rpm (within chroot to your normal
root file system from, say, a Live USB) that it thinks
kernel-2.6.18-348.18.1.el5.x86_64 is installed. Verify that there's a
directory /lib/modules/2.6.18-348.18.1.el5 with over 100 MB in it, and
that in addition to the strangely renamed initrd file, /boot has files
config-2.6.18-348.18.1.el5, symvers-2.6.18-348.18.1.el5.gz,
System.map-2.6.18-348.18.1.el5, and vmlinuz-2.6.18-348.18.1.el5. If the
latest SL5 kernel rpm is not installed, or even if it already is, you
could try installing or reinstalling it or an older one.
