That's a known issue which we *finally* managed to track down last week. Unfortunately this sched/urgent pull does not yet include those patches. If you want them, they can be had here: git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git sched/urgent I was meaning to push them to tip/sched/urgent on Monday, so they'd be in next week's batch. But if people want them now, have at :-)
