Did Soyuz TMA-11's equipment module not separate?

There appears to be growing evidence that TMA-11 suffered a repeat of an incident known to have occured in 1969 with the descent of Soyuz 5

Former Flight International contributor James Oberg has had an article published on IEEE Spectrum online that has information from an internal NASA report that indicates a fault with the separation of TMA-11's descent and equipment modules

Flight is also investigating sources that suggest that TMA-11 is not the only recent repeat of the Soyuz 5 equipment module problem
