I haven't stress tested this kernel too much, but I'm getting 4 uSec out of the box, so it works great for me. With numbers like 100uS, I would suspect something pathological, like SMI or legacy USB, or both. It could also be video, Precise is pretty happy installing proprietary video drivers. It is possible that there are some build options that are a little off for this machine, but I can't imagine what they would be to produce such large latencies. I second Kent's request for more info. ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
