This is the first time I hear about the regression. Joonsoo has pointed
out that there might be a problem but he didn't have any specific
failure in hands. The fix has been posted [1] and Andrew has picked it
up few days ago. Could you try to apply that patch? It will show up in
linux-next as soon as Andrew releases mmotm.
