Thanks, running for 300 seconds shows only a 2% error. Even running a I/O workload while running the massive_intr test keeps the same error. BTW, the system is more 'responsive'. For example starting applications while running the tests, switching windows, moving windows is much "smoother" than on default scheduler.
