I successfully use the sam9407-1.0.4 driver after a proper isapnp configuration, i.e. comment the hardwired IRQ9 line, compile the kernel, run isapnp. If there should be really no other purpose I recommend to comment the line, so I can use a precompiled kernel from now on. :-) kernel-source-2.4.26/arch/i386/kernel/pci-pc.c static void __devinit pci_fixup_piix4_acpi(struct pci_dev *d) /* PIIX4 ACPI device: hardwired IRQ9 */ /* d->irq = 9; */ Or maybe there is some method to deactivate hardwired irqs with boot parameters? My first experiments (without a clue about kernel internals) using kernel boot parameters like 'acpi=', 'pci=irqmask=0xMMMM' failed, though. Please CC me, if you want me to read your reply asap. All the best- Torsten Scheck
