Roger,
Are you using grub or lilo? Not that it matters but the config is a little different. Make sure you have the new kernel in the config file. Make sure you have the initrd to match your version of the kernel. If not use mkinitrd to create the initrd. Read the manpage for the syntax, it's pretty simple. I've never had this happen to me using up2date but that doesn't mean it can't. I don't use labels for my partitions, I typically just boot the root device so if you are using labels it may be a function of loading the modules using the ramdisk(initrd).

Sorry to partly hijack the post.
But I get the same thing when trying to run the current RH9 Kernel
All I did was get the new kernel as part of an up2date.
Why does it complain when the previous version was happy.
Please rename the thread if you feel the to are not related.
