For sure, there is not much point in starting on old code (the "stable" 2.6.16 series /may/ turn out to be an exception one day). An x86_64 port will be highly welcome! Feel invited to post I-pipe related topics also to [EMAIL PROTECTED] One hint that may ease testing/debugging: Have a look at qemu for x86_64. At least on x86, it already helped me a lot to debug weird kernel issues without long run-instrument-build-rerun cycles. All it takes is a minimal system image for a target. You can easily attach a debugger to the kernel, and you can even emulate SMP (though debugging is not perfect in that case). Of course, you cannot identify latency issues this way, but you will likely already be happy when things don't crash anymore. :) Jan
