(spuriously = maybe once every two hours with period = 500us) I'm using the trunk code and that error code is not mentioned in the rt_task_wait_period documentation. Any clues?

Already tried to run it at the same frequency? Does it fail as well? Further question: Does this error correlate with some real deadline miss of your application? SMI&friends might be a reason here, check delays of the testsuite (and your kernel config, of course). Is the workaround enabled? Is it reported to be used (kernel log)?
