I guess it is related to the fact that the "ubi_bgt0d" thread is frozen, and then the reboot notifier is called and this notifier tries to stop the frozen thread. Try to comment out thread stopping in the reboot notifier. It is not needed anyway. But I think I will remove this UBI reboot notifier, because it does not solve any problem, and it seems it actually introduces new problems. See this post: http://lkml.org/lkml/2010/2/12/114 Thus, if you confirm that commenting out the stuff in the notifier helps, I'll remove it.
