Have you tried running linuxsample at a higher priority? I would try
running it as sched_fifo, priority 60 or 70. You can use 'chrt' to achieve
that.

hwlat_detector is a kernel module. You just have to load the module and
tweak the values (though IIRC the defaults are sane) and let it run for a
while (at least 2h).

Have a look at /var/log/messages and dmesg and see if anything suspect
catches your eyes :)

Regards,
Luis
