Problems with pistachio

I have fixed the second problem but I would still like to have the answers
for the other two. I have modified the interrupt handling code so it is
easier to understand. The modified version of the code (with the exact same
problem) looks like this:

#include <l4io.h>
#include <l4/ipc.h>
#include <l4/schedule.h>
#include <l4/thread.h>

int main(int argc, char** argv){
printf("application started\n");
L4_ThreadId_t root = L4_MyGlobalId();
L4_ThreadId_t irq1 = L4_GlobalId(1, 1); // keyboard interrupt
L4_AssociateInterrupt(irq1, root);
while(1){
L4_Receive(irq1);
printf("interrupt received\n");
L4_LoadMR(0, 0);
L4_Reply(irq1);
}
return 0;
}

So can anyone tell me why this piece of code does not acknowledge the
interrupt?
