I both tested a configuration with CONFIG_XENO_OPT_SCALABLE_SCHED enabled and
an other disabled.
When I enable and when I launch the cyclictest, the system hard lock and the 2
left keyboard leds blink.
When I let it disabled the system is stable.

I've tested latency with loaded system (lot of applications loaded, dd, cp,
tar, find /)and have a max latency of 339us.
But I don't understand anything in the frozen trace file.

I've put this test in the test program to trace when max precision increase.
It's not the good manner to do, is it ?
if ((dt>dt_max)||(dt<-dt_max)) {
dt_max = dt;
xntrace_user_freeze(dt, 0);
