Hi guys, I wonder if anyone see this problem. When running 3.9-rc3+, the system is very sluggish. For example, on an almost idle system,

Dmesg and kernel config attached. It's a non preempt kernel(CONFIG_PREEMPT_NONE=y), maybe these days no one running non preempt on their system? I've not tried 3.9-rc1/rc2, will try to bisect this ... 3.8.x works fine.
