I have an issue where I receive a kernel panic/trace messages if I re-pair a wiimote immediately after turning the wiimote off. Whatever is causing this problem also disables bluetooth on my system and requires a system reboot to regain functionality. Normally if you turn off the wiimote, eventually the /sys/devices/ .... /bluetooth/hci0/hci0:xx directory will disappear after some time. However if you immediately re-pair the wiimote before this directory is removed you receive the kernel trace message and bluetooth enters a stuck state. I cannot restart the bluetooth daemon once I encounter this problem. A system reboot is required to use a wiimote again. The wiimote was originally paired with my Ubuntu system using the red sync button on the back. I usually just hit the A button to activate and re-pair the wiimote. I am running Ubuntu 12.04 64bit with 3.3.6-030306-generic kernel. I do see same problem with the default 3.2.0-29-generic kernel as well. I see similar issues if I try to pair two different wiimotes at the same time. Output from the syslog is below, any ideas or hints would be appreciated?
