I finnaly get the IRQ detection working with this patch,
in linux-2.1.102/arch/i386/kernel/irq.c :
unsigned long probe_irq_on (void)
{
unsigned int i, irqs = 0;
unsigned long delay;
/*
* first, enable any unassigned irqs
*/
spin_lock_irq(&irq_controller_lock);
for (i = NR_IRQS-1; i > 0; i--) {
if (!irq_desc[i].action) {
+ irq_desc[i].status = 0;
irq_desc[i].handler->enable(i);
irqs |= (1 << i);
}
}
spin_unlock_irq(&irq_controller_lock);
