Opal device may have an count in firmware to decide whether to resistent user input password. If yes, even correct password will be reject by device firmware. This count will be reset only after an cold reboot or user input correct password.
Opal driver also has an internal count to decide whether allowed user to input password. A reboot (code or hot) action will reset this count. Current implementation just base on the count in opal driver to decide whether allow user to input password again. In this case, if the count in opal device already exceeded, even an correct password will be rejected. New solution will check both count, either cout exceed will cause opal driver report count exceed and a shutdown required.
