/vendor/bin/hw/android.hardware.audio.service和/system/bin/audioserver的crash的原因都是一致得.
其直接原因都是由于audioserver发送的binder指令无法得到响应导致.

相关的log如下:

Cmdline: /system/bin/audioserver
pid: 30882, tid: 30951, name: TimeCheckThread >>> /system/bin/audioserver <<<
uid: 1041
signal 6 (SIGABRT), code 1 (SI_QUEUE), fault addr -------
Abort message: 'TimeCheck timeout for IAudioFlinger command 1'

这些binder指令无法得到响应主要是system died后导致的连锁反应.
具体可参考下边的log:
从22:30:40.015开始或甚至更早之前已经不停地报出DeadSystemException.
此时system应该处于died状态. 在这状态之前, audioserver, android.hardware.audio.service
以及别的一些指令长久没得到响应, 从而报了crash.
到05-20 08:20:43.157之后, system 重启完成, 之后就不存在这些crash了.
从此可以判断, system die了导致 audioserver, android.hardware.audio.service报出来的tombstone.
至于system为何died, 需要system组的同事帮忙分析.
