I have reported this bug here: http://bugs.opensolaris.org/view_bug.do?bug_id=6685676
I think this bug may be related, but I do not see where to add a note to an existing bug report: http://bugs.opensolaris.org/view_bug.do?bug_id=6633592 (both bugs refer to ZFS-8000-2Q however my report shows a FAULTED pool instead of a DEGRADED pool.)
