Which version of hostapd (and driver) are you using?

For some reason, the client did not send IEEE 802.11 ACK frame for the
authentication frame that the AP sent. Usually this happens when too
much time is used between the authentication frames. Wi-Fi certification
requires that stations wait at least 100 ms for this, but I do not know
what timeout values are really used. Are you sending that debug output
through serial console? Did you test the same thing with debugging
disabled? Which Prism2 card are you using? How fast is the host system?

Not much use in testing xsupplicant yet since even the IEEE 802.11
authentication failed.
