Nothing crazy here, unless we're getting the calculation wrong and
reading past the buffer, the code looks OK though. Or something like the
last page or so of that memory isn't actually free even though the
firmware tells us it is.
At this point, I think modifying the max address is the best way to
debug this further, and figure out what address causes the hang.
