Dig into the code and try to figure out what is happening. My best
guess at this point is that a block which is dirty isn't getting marked
as such, and therefore isn't getting correctly written back, but it
could also be that it tries to reconstruct a block before it actually
has all the blocks that it needs to do the reconstruction correctly.
