And it looks like the irqdomain code is the real culprit.
void irq_set_virq_count(unsigned int count) { pr_debug("irq: Trying to set virq count to %d\n", count);
BUG_ON(count < NUM_ISA_INTERRUPTS); if (count < NR_IRQS) irq_virq_count = count; }
That looks simply wrong.....
s/NR_IRQS/nr_irqs/ should do the trick.
Thanks,
