It sounds like Stephen has provided you the info you needed so not
doing any extra testing now, but I figured I'd chime in that I hit
problems this morning with linux-next and it appears to be the same
thing. I did a revert of 9984d7394618df9 and (plus a revert of a
handful of patches to the same file) and problems are resolved. The
failure case is really weird in that everything works well booting to
a simple /bin/bash but fails when you do more complex tasks.

Anyway: If you need some extra testing feel free to CC me.
