Comment 33 for bug 116752

David, thank-you for that revelation.

That indicates that the Bluetooth device-driver might not be doing everything it should when handling the PM suspend event, or it might be that the hardware is doing something unexpected that is probably handled as a quirk in Windows drivers (I assume the same doesn't affect Windows?).

Because the reports cover several systems and devices I don't think we are going to be able to easily determine if there is a common cause, or just a common symptom.
