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.

André

Scott,
actually I'm having trouble with my PCI interrupts.
We are running 2.6.26-rc6 on a MPC8343 based board.
There are two external PCI devices connected (FPGA + miniPCI socket).
The FPGA is working fine and uses IRQ0 for its PCI_INTA line.
As soon there's a miniPCI module present and the
interrupt-map = 0x5800 0 0 1 ipic 0x30 0x8 - FPGA @ IRQ0
0x6000 0 0 1 ipic 0x11 0x8 - miniPCI INTA @
IRQ1
0x6000 0 0 2 ipic 0x11 0x8;- miniPCI INTB @
IRQ1
Is it legal to use a single irq pin twice ?
The device tree simply describes the

software.
The outputs are open-drain and can be connected (wired-or) together.
Otherwise shared irq wouldn't be possible that easy.
cheers,

As soon there's a miniPCI module present and the driver loaded (actually
an ath5k WiFi module) the system complains after a while :
irq 48:
