No clue. It could also be a new issue introduced with a recent kernel change
(like all the fencing changes that have gone in). Or it could be an issue as
old as time itself :)

If this were easy to figure out, someone would have already done it. I haven't
a clue how to debug this... resume issues are notoriously difficult to
investigate.
