What error(s) do you get?
I'm not the original poster, but I appear to be having similar problems, though it's a panic rather than a failed consistency check. I posted about it back in July, see http://lists.freebsd.org/pipermail/freebsd-stable/2009-July/051167.html I've since gotten a serial console working (needed to use uart instead of sio), so I can now provide a backtrace, this from sources around 0600 UTC on 31 Aug. My gmirror is entire disks (ad6/ad4), and my ZFS pool/filesystems are still v6, on /dev/mirror/gm0s1d.
