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。
