We are pleased to announce the 2.6.25.4-rt6 tree, which can be
downloaded from the location:
http://rt.et.redhat.com/download/
Information on the RT patch can be found at:
http://rt.wiki.kernel.org/index.php/Main_Page
Changes since 2.6.25.4-rt5
- sched_cpupri hotplug support (Gregory Haskins)
- sched_cpupri prio count (Gregory Haskins)
- ftrace hotplug fix (Steven Rostedt)
to build a 2.6.25.4-rt6 tree, the following patches should be applied:
http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.25.tar.bz2
http://kernel.org/pub/linux/kernel/v2.6/patch-2.6.25.4.bz2
http://rt.et.redhat.com/download/patch-2.6.25.4-rt6.bz2
And like always, my RT version of Matt Mackall's ketchup will get this
for you nicely:
http://people.redhat.com/srostedt/rt/tools/ketchup-0.9.8-rt3
The broken out patches are also available.

I got this error message at compile stage. Also it is the same error
that was on -rt4. -rt3 compiles and runs fine.
