清帮忙分析一下，当前nightly环境能稳定复现。如果要环境请钉钉联系。
补充信息： arm上可通过，nightly目前依然失败
上游已知问题，nohz的情况下，idle time有概率回退 经过讨论，tglx认为该数字本来就不保证单调递增，讨论详见https://lore.kernel.org/lkml/87357q228f.ffs@tglx/ 后来进了一组patch，把该selftest的idle time递增断言给删了 https://lore.kernel.org/lkml/20230222144649.624380-8-frederic@kernel.org/ 故by design
