How likely it would be to get two requests with the same sector number I don't know. I wouldn't expect it to ever happen - I have seen it before, but it was due to a bug in ext3. Maybe XFS does it intentionally some times?
It certainly sounds like an odd thing to occur. Even stranger that it's easier to hit on a degraded array or an array being checked. I *am* using ext3 on this box (and all my boxes in fact)
You could test this theory by putting a WARN_ON(cfqq->next_rq == NULL); at the end of cfq_reposition_rq_rb, just after the cfq_add_rq_rb call.
I've done that.. now to wait for it to hit again.
