Fengguang, another test would be appreciated and > if it helps this series is the mm-numa-use-high-bit-v4r3 branch in > git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma.git Hi Mel, We noticed the below changes. The last_state.is_incomplete_run 0=>1 change means the test box failed to boot up. Unfortunately we don't have serial console output of this testbox, it may be hard to check the root cause. Anyway, I'll try to bisect it to make the debug easier.
