For those following this thread > you may want to start following that thread also. I posted a third approach last night. For those of you following this thread there are now three streams: This stream, https://lkml.org/lkml/2013/3/16/168 (which is also on the linux-pci list), and https://lkml.org/lkml/2013/3/21/12 (which is also on the linux-pci list). Perhaps the third time will be a charm -- 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/
