我们最近购买了一台翻新的 Dell 2950 II，用作我们实验室的开发箱。
安装操作系统（Debian Wheezy）并首次启动后，我在 DRAC 中收到以下错误，并且主机意外重新启动：
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).
此后，我在下次启动过程中收到以下内容（按相反顺序）：
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.

现在，奇怪的是，大约 75％ 的时间，它将无法启动并显示上述错误，而其余 25％ 的时间则可以正常启动。
重启总是在 GRUB 菜单之后发生，但在 Debian 开始发布典型的 syslog/boot 消息之前。
一如往常，我们将非常感谢任何帮助，谢谢！

尝试在 GRUB 设置中禁用帧缓冲区。您可以在启动字符串末尾添加“nofb”。我们在 Dell 2950 II 或 III 上遇到了同样的问题。
