I mentioned before that ftrace (specifically the ftraced daemon) seems to be

any regular calls to stop_machine() will end up confusing the load balancer.
As an experiment, I disabled ftraced (which would normally result in correct
load balancing) but added a single kernel thread which simply runs the
following loop, where "chrisd2" is a dummy function.
Chris,
Thanks for looking into this. I don't have an answer for your question, but I'll work harder to get the MCOUNT_REC working in PPC.
Does this happen with x86 too?
