I can't reproduce it here. It seems very odd that an ENOMEM would happen
as a consequence of the rq allocation change, it doesn't really change
the allocation at all (and it'll never return -ENOMEM).

Can you please recheck the git bisect results. It'd be nice if the
hibernation failure would actually log where the problem occured...
