Kernel 2.4.18 and non-Intel architectures

[Anthaus]

From www.linuxgames.com

"Version 2.4.18 of the ubiquitous Linux kernel was released; please note that it contains what's apparently a significant bug for non-Intel architectures (as noted in the changelog), so if you're using a non-x86 box you'll probably want to hold off on upgrading for now."

Does anybody can confirm or deny this?
Here's the changelog:

As for myself, I'm waiting until Red Hat releases their own kernel-2.4.18-x.athlon.rpm

In the meantime, that mem=nopentium fix is working great for me.

Is updating the kernel as simple as downloading then executing an RPM archive, followed by a reboot ?

Not quite.

If you have LILO you have to reconfigure the config file to load the new kernel.

If you have GRUB (as I do) the program reconfigures itself. So, yes, it's basically as simple as typing:

rpm -Uvh kernel-2.4.18-x.i686.rpm

As a general rule, you have to update your kernel-source as well (both versions MUST match!!!)

And finally, you may need to upgrade some other packages in order to upgrade successfully (modutils, compat-gcc, etc...). But there's no need to worry. If you have a failed dependency the process will be cancelled and your old kernel will still work fine.

Edit:
That's for Red Hat, BTW. I always get my new RPMs from the Rawhide folder:
