Hello,
I am encountering a strange situation. I have an application containing an
Xenomai task. When I run this application and at the same time start the
latency test. If my Xenomai task and latency task run on the same CPU core,
after a few minutes the whole system is halted. In case I do CPU affinity
to move my Xenomai task to another CPU core, it works fine (I have kept it
running continuously for 2 days without problem).
I have repeated this test with several kernel and Xenomai versions (kernel
4.4, 4.14, 4.19, Xenomai 3.0.8, 3.0.9, 3.1, xenomai-next) and obtained the
same result.
I have used Xenomai 2 for several years and have never seen such a
situation. Is this Xenomai 3 issue or a problem with my kernel
configuration?
Thanks for any help!
