java crashes on 2.4.21-20.ELsmp kernel

Has anyone seen a problem where /usr/bin/java seg faults using the
2.4.21-20.ELsmp kernel?

Here is a summary of the situation:

kernel: 2.4.21-20.ELsmp
java: j2re-1.4.2-9
system: Dell Precision 470n 2x3.2GHz Xeon

/usr/bin/java seg faults. Any application that uses Java will fail to

Add the noexec=off option to the kernel line of the SMP kernel you wish to boot from in /etc/grub.conf, for example:

title Red Hat Enterprise Linux AS (2.4.21-23.EL)
root (hd0,0)
kernel /vmlinuz-2.4.21-23.EL ro root=LABEL=/ noexec=off
initrd /initrd-2.4.21-23.EL.img

Save the file then reboot the system and try running java now.
