Can you create a wireless capture log showing this behavior? I would
like to see correct Beacon frames from the card and then the AP enabled
while the capture is running so that the Beacon frames from the AP and
change in the SSID in the IBSS case is included in the same capture.

Sounds more like a firmware issue thant something in the driver. Which
firmware version are you using?
