戴爾 2950 II 不可預知的引導失敗

我們最近購買了一台翻新的 Dell 2950 II 作為我們實驗室的開發盒。

安裝作業系統（Debian Wheezy）並首次啟動後，我在 DRAC 中收到以下錯誤，並且主機意外重啟：

Critical    08/09/2014 03:13:50 CPU 2 has an internal error (IERR).
Critical    08/09/2014 03:13:50 CPU 1 has an internal error (IERR).

之後，我在下一次啟動過程中收到以下資訊（以相反的順序）：

Critical    08/09/2014 03:15:41 A fatal IO error detected on a component at 
OK  08/09/2014 03:15:41 An OEM diagnostic event has occurred.

現在，奇怪的是，大約 75% 的情況下，它會無法啟動並顯示上述錯誤，而另外 25% 的情況下它可以正常啟動。

重啟總是發生在 GRUB 菜單之後，但在 Debian 開始發布典型的 syslog/boot 消息之前。

一如既往，任何幫助將不勝感激，謝謝！

嘗試在 GRUB 設置中禁用幀緩衝區。您可以在引導字元串的末尾添加“nofb”。我們在戴爾 2950 II 或 III 上遇到了這個確切的問題。
