could you check out the 2.6.15-rc7 version of the latency tracer i
uploaded to:

http://redhat.com/~mingo/latency-tracing-patches/

could test it by e.g. trying to reproduce the same VM latency as in the
-rt tree. [the two zlib patches are needed if you are using 4K stacks,
mcount increases stack footprint.]
