![帮助解释 lspci 输出 re: 2016 MacBook Pro 的暂停问题](https://linux22.com/image/1198826/%E5%B8%AE%E5%8A%A9%E8%A7%A3%E9%87%8A%20lspci%20%E8%BE%93%E5%87%BA%20re%3A%202016%20MacBook%20Pro%20%E7%9A%84%E6%9A%82%E5%81%9C%E9%97%AE%E9%A2%98.png)
我正在尝试确定为什么我的 MacBook Pro(2016 年末,MacBookPro13,1)在挂起/唤醒时会出现问题(多个)。这是我观察到的一个症状。
使用 dmesg,我在暂停后看到这些消息:
[ 820.490170] pcieport 0000:05:00.0: Unable to change power state from D0 to D3hot, device inaccessible
[ 820.490171] pcieport 0000:05:02.0: Unable to change power state from D0 to D3hot, device inaccessible
[ 820.491980] pcieport 0000:04:00.0: Unable to change power state from D0 to D3hot, device inaccessible
并最终
[ 820.553988] pcieport 0000:00:1c.4: Unable to change power state from D3hot to D0, device inaccessible
以下是 lspci 在挂起之前显示的内容。第一个输出使用 -nn,第二个输出使用 -t -nn。

我注意到 [8086:1578] 和 [8086:15d3] 设备(在 dmesg 日志中抱怨的设备)没有出现在这个树结构中。
最后,恢复之后,树结构就完全不同了。

我怀疑设备层次结构设置与挂起期间处理设备的顺序有关,存在问题。但我对此了解得不够多,无法自己弄清楚。
任何指示、提示、“获得线索”等都将不胜感激。谢谢!
