This happens when the application is running and there is hard disk activity. It happens also when latency test is running for a while. Linux 2.6.16 with Xenomai 2.4.6.1 works without problem. So this is solution for now. Tested on x86 - thinkpad laptop and pentium 4 desktop. I'm not a kernel hacker but surely try to help with fixing. I'd like to see this fixed. Thank you.
