We have a similar issue on Linux 4.4.87 and 4.4.113, with xenomai 3.0.5: https://github.com/RobertCNelson/ti-linux-kernel-dev/issues/16 (comes with code to reproduce issue).

It also may be helpful if you could provide some sort of sample code that reproduces the problem. -Greg On Mon, Feb 26, 2018 at 8:46 AM, <branislav.sa...@automatika.imp.bg.ac.rs> wrote: > Hello, > > I
