I can safely say that I have absolutely no idea, but I'm doubting it is mine.
Does everyone who hit the: kernel BUG at fs/notify/notification.c:93! have CONFIG_DEBUG_VM=N ? Mikko indicated that his problems seem to crop up with CONFIG_DEBUG_VM=N but not when he enabled it. I'll be testing again today with it disabled.....
