There is another way we could try. You began this entire thread by saying that this did not occur in 9.10. Can you verify that with latencytop and/or cyclictest, what are the maximum latencies there?
Assuming 9.10 latencies are way lower, it is possible to try to find the exact kernel patch responsible for this problem.
