如果 Thunderbolt 3 底座在挂起状态下拔出，则会冻结

如果我在 Ubuntu 暂停时拔下 Thunderbolt 3 底座，则下次尝试恢复时 Ubuntu 会冻结并出现黑屏。

这可以修复吗？

有一些错误和堆栈跟踪syslog：

pcieport 0000:03:02.0: can't change power state from D3hot to D0 (config space inaccessible)
thunderbolt 0000:04:00.0: can't change power state from D3hot to D0 (config space inaccessible)

正如这里所讨论的： https://answers.launchpad.net/ubuntu/+question/704136#5 解决方法是在挂起时卸载崩溃的驱动程序，然后在恢复时重新加载，以避免崩溃。

安装此脚本（来自这里），问题已解决：

# Original script was using /bin/sh but shellcheck reporting warnings.
