> Seems to me that either: > a) the pci_intack value is incorrect for your board, in which case you > should correct it Shure is, question is if it really should be caught from the pci_intack register, as far as I can understand from the MVME2600 doc's, the 8259 interrupt generates a MPIC-IRQ0, but one has to poll the 8259 to find out what device it was that generated the interrupt.
> b) your board's int-ack feature is broken and you'll need to poll Perhaps an extra field in the 'mot_info' (arch/ppc/platforms/prep_pci.c) is called for? This line in prep_init_IRQ (arch/ppc/platforms/prep_setup.c): i8259_init(0xbffffff0); /* PCI interrupt ack address for MPC105 and 106 */ does not look like a general solution. I'll take a further look in next week. Any comments/suggestions are welcome. .. Regards Anders Blomdell ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
