Philippe:

the exactly code is:
      if( 0 != adeos_virtualize_irq( irq[i], &rt_amcc_irq_handler, NULL, 
IPIPE_PASS_MASK | IPIPE_HANDLE_MASK) )

i want to handle and pass it down the pipe.

But i give propagate a try ... not realy better ... 
Now a second IRQ 4 will be delivert to the linux handler.
Only one IRQ 1 to the realtime (its masked out in PIC  when entering the 
realtime)
Could it be that this will block all other IRQ at PIC level ?
