更新：問題似乎出在內核 5.3.0-24 中，啟動到 23 時它工作正常。
從今天開始，我的 Kubuntu 19.10 系統在嘗試連線 wifi 時會掛起。在啟動時它顯示此錯誤：
iwlwifi 0000:03:00.0: Direct firmware load for iwl-dbg-cfg.ini failed with error -2
然後說
loaded firmware version 29.62a39462.0 op_mode iwlmvm
英特爾驅動程式已於兩天前更新，在出現此錯誤後，當我嘗試打開驅動程式管理員時，它不起作用 - 只是坐在那裡說收集有關您的系統的資訊。
我嘗試刪除該模組並重新加載它，但不起作用。在網上找不到任何內容來了解如何安裝或修復它。

我啟用了無密碼登錄，並停用了自動連接到 wifi 和用於顯示可用網路的網路小程序，甚至當我單擊連接到其中任何一個並提供 kwallet 密碼時，系統立即掛起，我不得不使用電源開關關機。

遇到同樣的問題。到目前為止，我的解決方法是切換回核心版本 5.3.0-23-generic。現在它按預期工作了。
