Complementing what Arnd said, we got the dynamic ftrace to work. Just changed 4 things in the *menuconfig*. Before these were built as modules (this is the default I guess): CONFIG_USB=m CONFIG_SOUND=m CONFIG_SND=m CONFIG_SND_USB_AUDIO=m
Then got them built into the kernel: CONFIG_USB=y CONFIG_SOUND=y CONFIG_SND=y CONFIG_SND_USB_AUDIO=y And everything worked just fine. In my config when I also tried to build the *CONFIG_SND_PS3* into the kernel, the kernel did not boot (probably another bug !? :-).
