我有一个 thunderbolt 3 基座，我正在运行 xubuntu 18.04。我遇到了类似的问题这个人，但我的内核是 4.18.0-18。我已经安装了该bolt软件包，我可以运行boltctl list并查看我的 dock：
o Lenovo Thunderbolt3 Graphic Dock
|- type: peripheral
|- name: Thunderbolt3 Graphic Dock
|- vendor: Lenovo
|- uuid: 00cdc88c-6e42-0801-ffff-ffffffffffff

当我启用基座（boltctl authorize或enroll）时，它的指示灯变为绿色，但随后我的计算机完全冻结，我需要按住电源按钮重新启动。
当这种情况发生时，我记录了 dmesg 日志，并得到以下信息：
