Subject: [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 ?
