It's almost certainly a deadlock through some path that wasn't tested.
Can you enable lockdep on that kernel when you run vmware, which should give us a nice callchain etc, and hopefully make it very obvious what goes on.
Reverting it is obviously an option, but with some more info maybe there's a better solution.
(It may be that the deadlock is obvious to Oliver/Greg even without any lockdep chains, of course, but still worth trying, I suspect)
