This code is still broken: you are checking only the first event-channel in
each bucket. You need a double loop: the new inner loop should iterate from
0 to EVTCHNS_PER_BUCKET-1.

ports = d->evtchn[bucket];
If ( ports == NULL )
    break;
for ( j = 0; j < EVTCHNS_PER_BUCKET; j++ )
  .... process ports[j] ....
