I don't see how these could be fixed in 2.0, its architectural, its like trying to backport a multithreaded stack into a Linux 1.1 kernel, just not feasible or worth it, just upgrade. But if you want to track all these down, report them to Redhat and see if they want to backport all the 2.2 architecture changes somehow and keep the 2.0 architecture intact, be my guest.EL4 is still supported, so if these are reproducable issues then reporting them would make sense, right? Or has this already happened?
