标题描述了我的问题。此外，使用“lapic”选项时，仅启用了一个核心。
尝试过 10.10(amd64)、11.04(amd64)
10.10 x86 版本无法使用 nolapic 选项启动。现在我使用的是 11.04 amd64 版本（已更新）。

谢谢您的任何建议。
答案1
这很可能是内核问题。但是通过 askubuntu 进行诊断很困难 - 我相信更好的基于论坛的平台会提供更具互动性的问答式场景来寻找答案。因此我的建议更通用。
既然您已经尝试过 lapic 作为启动选项，那么您还尝试过哪些其他选项？此链接包含一些您可能尝试过/可能没有尝试过的常用启动选项。在此处输入链接描述
有时在您的主板网站上查看可能会有更新的 BIOS 更新，您可以尝试一下。
有些人反常地发现 32 位 ubuntu 在 64 位 CPU 上表现更好，反之亦然。
查看 BIOS 选项。有时，出于某种原因，ACPI 被禁用。如果您有此选项（或类似“电源管理”的选项），请确保已启用它。
答案2
问题解决了。更换了相同型号的主板。一切正常。
