Thinkpad USB 3.0 擴充座斷開連接並重新連接

Thinkpad USB 3.0 擴充座斷開連接並重新連接

我有一台帶有 USB 3.0 擴充座的 Thinkpad T450s(也是 Lenovo),運行 16.04 LTS。該擴充座連接到一些 USB 週邊設備、乙太網路和 DisplayLink 顯示器。該站定期斷開連接,然後(非常快,約 1 秒)再次重新連接。這些事件通常每天會發生多次,但我之前也有幾天沒有發生過事件。據我所知,我的所有相關驅動程式(包括 DisplayLink)都是最新的。

我的 dmesg 也充斥著(我相信不相關的)垃圾郵件,無論擴充座是否斷開連接,這些垃圾郵件都會不斷出現:

[373168.536341] [drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x4000041, supported mask 0x7400003f
[373168.553436] [drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x41, supported mask 0x7400003f

由於 dmesg 垃圾郵件,我目前沒有斷開重新連接的日誌。當我能夠捕獲它時,我將包括一個,但我不相信它顯示除了連接到擴展塢斷開連接然後再次重新連接的設備列表之外的任何異常情況。

謝謝!

編輯:斷開連接後立即來自 dmesg 的結果如下:
