■ 下一步计划
与 #118571 一样, 需要结合着一起看一下

[当前状态]
分析traces_SystemServer_WDT07_06_10_18_02.563_pid1547
system_server的主线程，android.fg线程都是被Binder:1547_3线程block

而Binder:1547_3的状态呢？

Binder:1547_3线程在启动Activity的过程中，会获取唤醒锁，为了防止设备在启动activity时进入睡眠状态，以确保启动过程的顺利进行。
if (!uiSleeping && !mAtmService.isSleepingOrShuttingDownLocked()) {
mStackSupervisor.acquireLaunchWakelock();
}

Binder:1547_3线程在通过PowerManagerService获取唤醒锁（wakelock）的时候调用到BpHwSystemSuspend服务，BpHwSystemSuspend服务进行跨进程调用的时候没有返回。

解析以下2个内存地址:

代码中没找到SystemSuspendAll.cpp，应该是以so库提供的。

[下一步 Action]
接下来需要BSP同学分析下造成BpHwSystemSuspend跨进程通信失败的原因。是写入节点失败了吗？

Hi，
@杜磊，如前面分析所示，现在怀疑应用在申请WakeLock时，通过如下堆栈调到了HAL层，卡在了某个环节上，需要bsp的同事帮忙分析下具体的情况。

申请WakeLock的调用堆栈如下：

Hi all

分析此问题，需要在system_server anr后获取对应的ramdump，进一步排查binder卡住是主从哪端的问题。

需要使用如下VB进行专项测试，当system_server触发watch dog后，会主动给触发ramdump。

ftp://cdiot@192.168.87.46/Pre_figure/VerifyBuild/Pre_figure_turbox-c2130c-la1.1-qssi12-dev/20230609/202306091536-4284/FlatBuild_HH_MCE_FSE.M.D.user.01.00.C104%28X104%29.202306091536.zip

日志文件参考：

----- pid 1496 at 2023-06-06 13:54:20.947954659+0800 -----
Cmd line: system_server

./logcat/000156_persist_04790_230606_135511.log:885:06-06 13:55:55.820  1496  1608 W Watchdog: *** WATCHDOG KILLING SYSTEM PROCESS: Blocked in monitor com.android.server.power.PowerManagerService on foreground thread (android.fg), Blocked in handler on main thread (main), Blocked in handler on display thread (android.display), Blocked in handler on animation thread (android.anim), Blocked in handler on PowerManagerService (PowerManagerService)

本地验证：

--adb shell
--su
--am hang

设备等待一会触发system_server watch dog,使用对应VB 符号表可以进行解析
