A couple of questions. How bad is it if you just run with irqpoll in the kdump kernel? If running with irqpoll is usable that is probably preferable to putting in a hardware work around we can survive without. Have you done any looking at moving where the kernel initalizes io_apics? One of the todo items on the path is to leave io_apic mode enabled and just startup the kernel in io_apic mode. When doing that a version of your work around (if needed) would certainly be reasonable. My general concern is that the trickier we get in the code running in the crashed kernel the less reliable the entire process will be. Eric
