Hairworks crash on Multithreaded Rendering

Every time when I try render hairworks model in several threads (each has own deferred context) I got app crash with this error:

D3D11 CORRUPTION: ID3D11DeviceContext::VSGetConstantBuffers: Two threads were found to be executing functions associated with the same Device[Context] at the same time. This will cause corruption of memory. Appropriate thread synchronization needs to occur external to the Direct3D API (or through the ID3D10Multithread interface). 88996 and 89196 are the implicated thread ids. [ MISCELLANEOUS CORRUPTION #28: CORRUPTED_MULTITHREADING]

Are the hairworks allow multithreaded rendering?
