Such hangs happen when I/O never returns. ZFS doesn't timeout I/O requests on its own, this is driver's responsibility. It is still strange that the driver didn't pass I/O error up to ZFS or it might as well be ZFS bug, but I don't think so. --=20 Pawel Jakub Dawidek http://www.wheelsystems.com pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
