That implies the IRQ routing is failing which usually but not always means the tables in the firmware are wrong. The first step would probably be to dump all the relevant PCI register space and the ACPI tables and compare them with the IRQ routing documentation for the chipset. Actually no - thats step 2, step 1 is asking the vendor if there is updated firmware to fix IRQ delivery problems -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
