我们最近购买了翻新的戴尔2950 II作为我们实验室的开发盒。
在首次安装操作系统（Debian Wheezy）和引导之后，我在DRAC中收到以下错误，主机意外重启：
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). 之后，在下一次启动的过程中，我收到以下内容（以相反的顺序）：
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. OK 08/09/2014 03:15:41 An OEM diagnostic event has occurred.

现在有一个奇怪的是，大约有75％的时间，启动失败，显示错误，另外25％的启动正常。
重启总是在GRUB菜单之后发生，但是在Debian开始发布典型的syslog / boot消息之前。
一如往常，任何帮助将不胜感激，谢谢！
尝试在GRUB设置中禁用帧缓冲区。 您可以在引导string的末尾添加“nofb”。 我们在戴尔2950 II或III上遇到了这个问题。
