具体表现
reboot老化的过程中，reboot的过程被暂停了，并且进入了standby
问题分析
在reboot老化的时候，关闭休眠
从kernel的log来看，安卓层先发起了reboot，内核也收到reboot的消息
#1[2023-07-11,16:56:45][ 41.176369][ T164] init: Received sys.powerctl=‘reboot,’ from pid: 490 (system_server)
[2023-07-11,16:56:45][ 41.185428][ T164] init: sys.powerctl: do_shutdown: 0 IsShuttingDown: 0
同时从安卓的log来看，安卓层也会有息屏关机的动作。
所以这个时候是刚好在reboot的过程中，安卓执行休眠打断了reboot并且休眠成功。一般建议做reboot老化的时候要关掉休眠，之前也出过类似现象。
