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！
