I have done some minor debugging and it fails on the call
rt_task_make_periodic during
the insmod function. I tried to put in some printk but that didn't work I
noticed a
conpr function which I assume is a console print but didn't know how to use
it. I tried and was unsuccessful. Also where is the source for switch.o .
Any help in how to troubleshoot this would be appreciated.
