NUC 與 Centos 7 崩潰：檢測到微碼 SW 錯誤

  • July 22, 2019

我試圖弄清楚為什麼我的英特爾 NUC 上的 CentOS 7 上的 WiFi 繼續當機。作為資訊，我有 5 個節點的 Hadoop 集群，它們都配置相同（據我所知），但是，WiFi 上的其他機器不會崩潰。我不知道這台機器出了什麼問題。

這是來自 的錯誤/var/log/messages。這是我經常看到的相同消息，因為我已經觀察了這個問題好幾天了。

我應該從哪裡開始嘗試調試？我可以編輯帶有更新的原始文章。

以下是一些我認為可能會有所幫助的事情：

似乎 wifi 驅動程序無法管理 NUC 中的 wifi 硬體。

  • 幾個 linux 發行版可以在不安裝的情況下實時試用。我認為 NUC 有 Intel wifi，它應該可以與內置的 linux 驅動程序一起使用，但它們必須足夠新。
  • 我有一個帶有英特爾第 6 代硬體的 NUC。我注意到舊版本的作業系統無法管理 wifi 硬體，但新版本無需任何調整即可管理它，“開箱即用”。
  • 編輯 1：我使用實時系統進行了測試：Ubuntu 18.04.1 LTS 可以管理我的 NUC6i3SYH 的有線和無線硬體。Debian 9，Stretch，可以自動管理有線網路。我的 wifi 失敗了，但其他人可能會修復它（我不知道是否存在驅動程序問題，或者我是否無法在 Debian 中管理 wifi 的使用者界面。）
  • 編輯 2：我下載CentOS-7-x86_64-LiveGNOME-1810.iso並實時執行它，它可以管理我的 NUC6i3SYH 的有線和無線硬體。它的啟動與使用 Ubuntu 18.04.1 LTS 一樣容易。但是我很久沒有測試穩定性了。

編輯3：您應該考慮硬體可能已損壞（例如變熱時失敗）。但是，如果它與其他作業系統一起執行良好，則可以得出硬體良好的結論。

  • 你的 NUC 硬體是什麼時候開發的，CentOS 7 軟體是什麼時候開發的？
  • Centos 7 有一個舊的核心系列，3.10；實時系統“1810”中的核心版本是3.10.0-957.el7.x86_64 #1 SMP. Ubuntu 18.04.1 live 具有核心版本 4.15.0-29，最新安裝的系統具有 4.15.0-43。
  • 請嘗試使用具有較新 linux 核心和較新硬體驅動程序的另一個作業系統。
