The related interrupt pin of the PIC / APIC isn't after the request_irq() call reconfigured for handling of an ISA interrupt ! The ISA interrupt is connected to a pull down resistor ... which leads to a catastrophic crash when that ISA interrupt line is handled as a PCI interrupt line. Is this by design - that means no ISA interrupt supported - or is it a bug ? --Armin
