我的 Thunderbolt4 端口无法工作，如何验证这是硬件还是操作系统问题？

我在 Lenovo ThinkPad P1 Gen 4 上使用 Fedora 38。内核版本是 6.3.11。我的 Thunderbolt 4 端口似乎已通电，但无论我插入什么端口，都没有输出。有什么方法可以验证这是由于硬件还是操作系统缺乏支持造成的？

更多背景

该端口曾经工作正常，这就是我怀疑硬件故障的原因。我曾经将联想坞站连接到它，但有一天它停止工作了。以下是我用来检查操作系统是否仍能看到端口的一些命令：

boltctl list -a

该扩展坞是我拥有的唯一 T4 设备，如果将其插入，我会得到空白输出boltctl list。我还尝试插入标准 USB-C 随身碟，但也没有被检测到。

跑步journalctl -u bolt给了我：

如果您对我还可以运行什么来调查问题有任何建议，请告诉我。

答案1

我仍然不知道是什么导致了这个问题，但是执行以下操作解决了问题：

  1. 关闭计算机电源。
  2. 将其从电源上拔掉。
  3. 使用位于机箱另一面中间的针孔重置按钮。保持10秒
  4. 插上所有东西并通电。

使用此针孔重置不会影响文件系统或其他任何内容。这似乎是一次硬重置，删除了内置电池型号中所有子系统的所有电源。 P1手册指出，当标准重置不起作用时，您可以使用它。
