If it's your first time with the rt-kernel then you should download
the 3 file set that Thomas announces for each kernel. One thing you do
NOT want to do is mix and match in ways that the rt-developers don't
suggest. Note that the rt-kernel should always (AFAIK) be built only
against the kernel.org kernel with the same base revision number.
Here's a recent announcement:
<QUOTE>
We are pleased to announce the next update to our new preempt-rt
series.
- include the futex rework + requeue_pi support (Darren Hart)
The futex changes need profound testing. As we know from prior futex
work the best stress tests for the futex interface are RT-Java-VMs
especially with enterprise work loads on larger machines. Can the
folks who have access to such monstrosities please unleash the beasts
and give the futex code a good work out ? Please tell your sysadmin
upfront that he should be stand by to fix up the resulting wreckage
which might vary from harmless to system replacement.
Unfortunately I was not able to track down the weird 32bit PAE
shutdown crash, so the affected users need to stick to the
nosmp-alternatives work around for now.

Information on the RT patch can be found at:
http://rt.wiki.kernel.org/index.php/Main_Page
to build the 2.6.29.1-rt5 tree, the following patches should be
applied:
http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.29.1.tar.bz2
http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.29.1-rt5.bz2
The broken out patches are also available at the same download
locations.
Enjoy !
