plain 2.4.24 kernel / RedHat ES 3

[jullrich at euclidian.com (Johannes Ullrich)]

I ran into a very frustrating problem today. It all started out with
trying to setup a grsecurity patched kernel on a RedHat ES 3 system....
However, as it turns out, it wasn't grsecurity in this case that broke
things.

Symptoms: 
basic RedHat ES 3 install, dual CPU intel hardware.
If you replace the kernel with an unpatched 2.4.24
kernel, the system boots fine, but it looks like some programs (e.g.
host, dig are two that pointed me to the problem) can no longer fork.
They just segfault.

Has anybody found a way around this?

As mentioned in the intro, the goal of this is to setup a grsecurity
patched kernel. I usually just patch a vanilla kernel, as the patch will
not apply cleanly against the RedHat source tree (many, many .rej files,
some of which are in code I don't want to touch)

I got RH 9 systems running with no problem, but they are all single CPU.

Workarounds?
