RHL 5.8.1 (beta 1) kernel-2.2.1-4 and kernels compiled against kernel-source-2.2.1-4 fail to boot. During the system startup they system hangs when it says Finding module dependencies I figured this must be a kernel problem; the original kernel-2.2.1-2 kernel does not have this problem
This was a problem with the modules' version information. It should be fixed now.
