You can simply build the latest kernel, recommended is to use a full
preempted with threadirqs enabled or a kernel-rt.
This script is a little bit "dirty" and I edited it after copying it to
this email, but it should build 3.6.5-rt14 and easily can be edited to
build another kernel, but you need to edit more than just the variables,
to do that ;), again, it's a "dirty" script.
