That is not good. You will need to compare the patch code and the existing kernel code. Maybe parts of your preempt patch code is already in the Fedora kernel source.
Hmmm. I found this link:
http://rpmfind.rediris.es/rpm2html/fc2-i386-updates/kernel-doc-2.6.8-1.521.noarch.html
that says that the voluntary preemption patch has already been added but the instructions to enable voluntary preemption from http://wiki.philkern.de/5.html
echo 3 > /proc/sys/kernel/voluntary-preemption
fail because the file doesn't exist. So I'm not sure whether it has or hasn't or perhaps there a step missing.
Steve.
