这是一个非常奇怪的问题。我在一台机器上安装了 Ubuntu 10.10 x64，每个 PS/2 设备（更准确地说是鼠标和键盘）几分钟后就停止工作了。
我该如何诊断这个问题？
这是输出lspci：

答案1
你很可能患有一个已知的错误似乎已经存在一段时间了。我自己也曾遇到过 Lucid 中的这个错误，但升级到 Maverick 后就解决了这个问题。
我发现了一个可行的解决方法，可以防止 10 次中有 9 次出现冻结。我只需在启动后直接登录 Gnome-Failsafe 会话，等待一分钟，然后我就可以登录正常会话，而不会冻结 PS/2 设备。
最后看来是 X 的问题，因为我可以正常在终端 (tty) 上工作，但是当我切换回 X 会话时，设备再次冻结。
