I tried to install the 2.6.9-1.724_FC3 kernel with yum and it answers: Transaction Check Error: package kernel-2.6.10-1.766_FC3 (which is newer than kernel-2.6.9-1.724_FC3) is already installed package kernel-2.6.10-1.770_FC3 (which is newer than kernel-2.6.9-1.724_FC3) is already installed I have 2 other machines, one FC2 and one FC3 which have both 2.6.10 and 2.6.9 installed and that I boot with the 2.6.9 due to performance issues with postgresql. Yes, it has the 2.6.9-1.667 installed but I would like to use the last 2.6.9 from Fedora. How to install the 2.6.9-1.724_FC3 kernel?
