Attaching the entire log from the testrun. | It indicates that in each run of the 10000 iterations, there are about 100+ | failures, with large iterations.

You might wanna check signaltest: git clone git://git.kernel.org/pub/scm/linux/kernel/git/tglx/rt-tests.git rt-tests Regards, Luis -- [ Luis Claudio R.
