Red Hat is constantly making new innovations, improving and fixing bugs in our software. This is especially important for the kernel as it contains drivers for many devices. Old kernels can suffer from kernel crashes/hangs, network interface flapping, bonding problems, IO performance and networking problems and many others, which may have been fixed in more recent releases.
