Thank you for the message. I now can see that I was not clear enough. I am not trying to use a single kernel for both distributions. I'm using two separate kernels for each. Right now Debian's GRUB gives me the option to boot kernel 2.6.26-1-486 for Debian, or kernel 2.6.22-14-generic for Kubuntu. I am simply trying to change the Kubuntu option to 2.6.24-22-generic. But for some reason changing Debian's menu.lst for Kubuntu from 2.6.22-14 to either 2.6.24-19 or 2.6.24-22 results in a boot that hangs.
