I'm trying to install the 2.6.18 kernel from the /testing folder on a clean Slackware install. I've followed Pat's directions to the T from his README.initrd file that accompanies the packages.
did you try installing an alternate kernel as i mentioned in my page. (link is given in 1st post)
1. did lilo returned an error?
2. did you manually copy the kernel bzimage? and renamed as vmlinuz-generic-2.6.18 or it is somehting else?
i think you linked the wrong stuff as the image, in lilo
most probably it is not an initrd problem, so dont worry about initrd.
your kernel is not uncompressing that means u pointed the wrong stuff as the kernel image hope i am right
