This needs to be fixed (perhaps worked around in UML if that's 
possible and if you agree with that) - or barring a real obvious fix 
needs to be reverted to the last-known-working state. We are in -rc9 
so nothing but really, really obvious patches can be applied.

No, your complaint is entirely justified.
