Hi Xu Zhe, If I were you I would first of all check cables. They might be the cause. Secondly, if cables are good, to me this report very much resembles a PR I reported a few weeks ago - http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/179926 Check its set and look at the patch I submitted. It's a pity there's no response to it.
