Sounds pretty simple to me. If you are using lilo, then you might not be rerunning lilo after installing the new kernel. Also, after installing a new kernel you need a new initrd image. Your unresolved symbols problem is because you are trying to load the ext3 module from a 2.4.7-10 kernel in the 2.4.9-13 errata kernel. The general answer here is that there is significant documentation on what must be done to upgrade a Red Hat kernel. Read it.
