On TSC calibration, as I read it, it is only the fast calibration which fails, not slow (regular) calibration. Both have "Marking TSC unstable due to TSC halts in idle" logged later, and I have no idea whether that is significant, although I suspect not. (Amongst other things, it would not explain why b43 works on a warm boot.)
