Updated kernel, but new kernel doesn't start


I updated my RHEL 4 kernel via up2date and rebooted the computer, but I uname still shows the old kernel and the Red Hat Network Alert Notification tool tells me that I need to reboot to make it work. I have rebooted several times, but the new kernel doesn't run. I've been looking through Red Hat docs and everywhere else I can think of, but everything I find says simply to restart. Am I missing something?

I am also beginning to think that this was an ill-advised update. I know up2date is supposed to have preserved the old kernel (and indeed it is the old one that is running) -- at this stage, if I choose to remove the new one from my system and stick with the old one is it is simple matter of running rpm -e on each of the kernel .rpms?

Thanks for the help!

Have you looked at your "/boot/grub/menu.lst" file to see if the new kernel was added? You might also want to run "ls -l /boot" to see if there is more than one set of kernel files.

Thanks.

The new kernel is not listed in /boot/grub/menu.lst and I have only one set of kernel files in /boot (those for the old kernel).

At this point I think I would prefer to just stick to the kernel that's running. I'll go all the way with the update when I have more time in case I end up breaking the machine. How should I roll back (as it were, since the new kernel never seems to have been fully installed)? Can I just do an rpm -e on the new kernel files?
