Intel wifi5300 sends an incorrect Registrar Nonce

I'm running WPS with hostapd-0.7.3 and an External Registrar on the
following environment and come across a failure of Registration Protocol.
Kernel : 184.108.40.206-88.fc7
Distribution: Fedora 7
Registrar : Windows Vista
When I use Intel wifi5300 (Driver Ver:13.5.0 ) as an Enrollee, it
responds a WSC-ACK including an incorrect Registrar Nonce after
hostapd sends M2D to wifi5300. The Registrar Nonce is the same as used
in the previous Registration Protocol session.
Is there anyone experiencing the same phenomenon?
This phenomenon seems to apparently ascribe to the Intel's chip
implementation. However, if hostapd waits for an External Registrar
sending a PutWLANResponse before starting sending M2/M2D, hostapd will
get a valid Device Password and send M2, not M2D. How do you think?
