When I upgraded to Xenomai 2.2.4, I tried the switchtest program:
cd /usr/xenomai/testsuite/switchtest
./run
The program appeared to run properly, but <ctrl>-c would not stop the
application. I was not able to kill the process cleanly, and
/proc/xenomai/stat showed lots of processes still running.
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
