I get the same result with svn trunk (rev 1749) plus this FPU patch:

  https://mail.gna.org/public/xenomai-core/2006-10/msg00069.html

I think the bug may be SMP related.  When I press <ctrl>-c the first time, I see no more references to CPU 0.  When I press <ctrl>-c a second time, all output stops.  I have attached the output below.

Thanks,

Jeff


[root switchtest]# ./run
