It is detailed, but in all the wrong ways: instead of describing the problem that he's seeing and offering data, he has jumped to a code path that he believes is inducing it -- without much in the way of supporting evidence. And yes, he talks about bad HW ("access to the second port on the card currently fails to acquire swfw sync"). The ensuing discussion is more of a desultory wandering than it is a deliberate investigation into his problem -- which isn't surprising, because he hasn't described a problem but merely an observed artifact in the system. (Long lock hold times can easily be misleading; when exploring latency bubbles, one needs to be very careful about tying observed behavior to the latency outliers, lest one discover problems without discovering "the" problem.)

So yes, I stand by my summary of the thread.
