I was trying to get the rt_task_periodic functions to run using the
2.0.36 applying patch .9J.
I got the following stack trace when I tried to run the example under fp
(have other app where I was
also getting core dumps when I try to start periodic function).
/sbin/insmod trigmod
[root@simpc15 fp]# ./trigapp

I did mod "rt_task_make_periodic (&tasks[0], rt_get_time ()+1000,
5000); " I added the 1000
because it crashed without it tried to initiate it right away I guess
anyways crashes with or without
it. If you tell me what to look for in the kernel code would be happy
to do some
debugging if you could give me some guidance where to look 3c509 is my
