Scott,
thanks for your reply.
Honestly I don't think the board wiring is incorrect.
FPGA goes to IRQ0 and miniPCI is wired to IRQ1.
Maybe there's a crosstalk problem since the pull-up resistors are
packaged inside an array ... I'll check this.
regards,
André

The FPGA is working fine and uses IRQ0 for its PCI_INTA line.
As soon there's a miniPCI module present and the driver loaded (actually
an ath5k WiFi module) the system complains after a while :

Segher,
actually I'm the hardware designer ... :-) having trouble with
software.
The outputs are open-drain and can be connected (wired-or) together.
Otherwise "shared irq" wouldn't be possible that easy.
cheers,
André

Is it legal to use a single irq pin twice ?
