I call cyg_drv_interrupt_acknowledge in my isr just after interrupt_mask and 
after more 50 interruption, this function fails when it calls 
hal_interrupt_acknowledge(int vector) and the reason is that arg vector is 
corrupted (vector = -1 instead of 7). In fact, I thought that my stacks size 
(more than 20 threads in my code and about 10 isr) is not enough and i increase 
their size but this did not resolve the problem. Separate stack for interrupt 
is disable.
If someone can help!
Thanks!
