Devices failed to connect. hciconfig showed a controller with all-zero BD address. I reverted the commit as well as bd003fb338af that depends on the commit. It made the problem go away. I know virtually nothing about bluetooth. Let me know what info you need to debug the issue. -- Kiryl Shutsemau / Kirill A. Shutemov
