You might run into trouble here on the ES7000 -- though I don't know if anybody is booting a modern kernel on one of those these days. IIR, ES7000 treated the bottom 16 as a special case. When there was an irq shortage, I think they used overrides to map higher PCI irqs into the empty spots below 16, but I think to make room for them they may have mapped some of the ISA irqs to high numbers. Fuzzy memory on this at the moment... cheers, Len Brown, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
