Why is it I cannot use fbsplash using the grsecurity kernel patches? I have downloaded kernel 2.6.14.6 (http://www.kernel.org/pub/linux/kernel/ ... .6.tar.bz2) and applied the grsecurity patch of http://grsecurity.net/grsecurity-2.1.8- ... 7.patch.gz and extracted it. I applied it using patch -p1 < grsecurity-2.1.8-2.6.14.6-200601211647.patch. It applies sucessfully. However, when I downloaded http://dev.gentoo.org/~spock/projects/g ... -rc2.patch and applied it the same way I get some errors.

I just want to use grsecurity with fbsplash... Is it the poor quality programming of Spock or the grsecurity staff?

You try to apply a patch for 2.6.16-rc2 (fbsplash) to a 2.6.14.6 kernel. That won't work. Try http://dev.gentoo.org/~spock/projects/g ... 6.14.patch from spocks directory.

I can apply each patch fine successfully by themselves. It is when I try to apply both to the same kernel I recieve the error. This indicates grsecurity and fbsplash patches chage some of the same files and such.

Sorry but i can't verify your problem. Just downloaded kernel 2.6.14.6 , patched grsec and after that patched fbsplash. Only 1 chunk didnt't apply cleanly und this one is easy to fix.
