It is true, in very special cases, that someone might need to compile a
generic kernel for their installation. Here is what RedHat thinks about
a paying customer who does that:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=122528
You can also use LD_ASSUME_KERNEL=2.4.1 to turn off NPTL ... which might
help after you compile your own kernel (or might make your application
run under RHEL without rebuilding your krenel, and allow you still have
a supported kernel).
But I still think that (except in very, very unique cases ... where it
is absolutely required) you should use a kernel that comes with the
distro. When new packages are released, they are going to be built on
the assumption that you are running a kernel that was provided.
Building your own generic kernel will cause problems in the future with
updates ... But, in some unique cases, it might be required to compile
your own generic kernel. I just want to make sure anyone thinking about
doing that understands the potential issues with making that decision.
If you were actually running RHEL AS 3, RedHat wouldn't even talk to you
about that box until you reinstalled their kernel ... but you would
still be required to pay them the $1499 (minimum).

Why use a standard kernel? One reason could be you want to convert your machines
