Yeah it's missing a call to cpu_timer_sample_group() before clear_dead_task(). Andrew Morton reported the warning and I have a pending patch to fix that. I'm just checking a few other things before sending it. These clear_dead_task() calls seem to also conflict with cleanup_timers(). I'm fixing that too.
