It builds and runs fine on my Icecube-MPC5200 board, now also with the
latency tracer enabled. That's great. Still, "cyclictest -n -p80 -i1000"
reports latencies up to 400 us and therefore I tried to trigger and save
a high latency trace using:

  # ./cyclictest -n -p80 -i1000 -b400
  1.21 0.33 0.11 4/42 1048

  [   91.042169] (      cyclictest-914  |#0): new 39733427 us user-latency.
  bash-3.00# cat /proc/latency_trace > trace.log

Well, I'm not sure if this is the correct way to do it. Is there some
doc on how to use the latency tracer and interpret the results?
Nevertheless, I have attached the beginning of trace.log. Maybe it rings
an experts bell.

TIA.
