Thanks for the help Scott. Simply getting my irq from the pci device structure in my probe callback following successful PCI driver registration was the trick. I now have my Fujitsu CoralP driver running under the 2.6.24 kernel on the Lite5200b (although I have a HW problem on my product board that confused my efforts). Regardless, I'm now confident I'm doing this correctly, thanks to you help.

No, clearing interrupts is device-specific. Have you verified that the device does not think it's generating an interrupt during the interrupt storm? Do other PCI cards work? -Scott _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
