You are running an SMP kernel, is this really what you want ? (note
that this is unrelated to the problem you have).

Does it work if you call rt_intr_enable after rt_intr_create ? 
If no, does it work if you call request_irq for the same interrupt ? 
If yes, does it work work if you use the I-pipe kernel from the
for-ipipe-3.14 branch of the ipipe-gch git repository ?
