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!
