[PC/104 interrupt bug] Fedora 13 problem

Hi,

I'm developing a driver for a PC/104 board and see that the flag IRQF_TRIGGER_RISING has no effect with
a request_irq() call.

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 ?
