[Xenomai] Stack Overflow when changing Affinity

2018-01-09 Thread Henry Bausley 
We have an application that gets run repeatedly that causes a stack overflow.  
The source is at the end of this mail.
We have tracked it down to changing the affinity.

We have used xenomai 2.6.5 and 2.6.4 and kernels 3.14.28 and 4.1.18 and seen 
identical results.  Our platform is an LS1021A NXP/Freescale ARM processor.  Is 
this a bug or are we incorrectly using affinity

Subject: Xenomai community meeting 02.02.18

Hi,

we have already talked about the "elephant in the room" and in that
thread we also talked about a face-to-face meeting of current and
future maintainers, contributers and users.

We have now agreed on a time and place for this meeting, and i want to
announce it and invite the whole community to it.

Where: somewhere in Brussels (details will follow)
   and remotely, TelCo link will be published
When: 02.02.18 13:00-18:00 (CET)
What: we do not have a clear agenda yet, but there is probably enough
  material to fill the timeslot
Attendees: Philippe Gerum, Jan Kiszka and myself will be there, you as
   well?

That meeting is colocated with https://fosdem.org/2018/ if you are
planning to attend in person, keep that in mind and maybe stay the
weekend. Jan and me will be around until Sunday afternoon, Phillippe
will leave Brussels on Saturday.

Sorry for the short notice, i still hope more people will attend in
person or at least in the TelCo. We will rent a coworking space for the
meeting, so the location depends on the number of participants.
If you want to participate please answer this mail before 01/24/18.

Looking forward to the meeting!
Henning

Hello everybody,
I've looked up at 
https://xenomai.org/pipermail/xenomai/2017-November/037941.html and got 
the same situation.
I was wondering if something has moved since November about Debian and 
3.0.6.

Thanks,
