内核软件包升级后，bumblebee 出现了问题。这个问题从 12.04 版开始，一直延续到 13.04 版。
基本上概括如下；在全新安装 ubuntu（无论哪个版本）后，我安装了 bumblebee，它开箱即用。当内核升级（例如从 3.8.0-19 升级到 3.8.0-22）后，一段时间后，bumblebee 会崩溃，并出现以下错误/var/log/syslog：
kernel: [ 4.135691] bbswitch: Unknown symbol mcount (err 0)

此问题最近已发布这里但没有发布解决方案。此外，它不同于这问题。
目前，到目前为止，我发现的唯一解决方法是重新安装 ubuntu，升级到最新的内核版本，然后安装 bumblebee。此后，它运行良好，直到下一次内核bumblebee 升级时，它会再次崩溃，我必须重新安装。这远非最佳，因为我必须大约每 2 周这样做一次 :(。
一些信息：
Ubuntu 13.04; kernel version 3.8.0-22-generic
Clevo W150HR, i7 2630QM, NV GT555M, 8GB RAM, SSD+HDD
有人知道如何修复这个问题吗？
编辑：结果发现这是 gcc 版本过时的问题。
答案1
正如所讨论的，这似乎是 gcc 旧版本的问题这里。
在 gcc 4.4 下安装将会中断，但在 gcc 4.7+ 上可以正常工作。
