我的 Ubuntu 死机了（没有响应，鼠标/键盘和桌面都显示旧时间）。这种情况每周发生一两次。我还没有找出真正的罪魁祸首，但日志包含以下错误消息：

根据 Google 搜索，AE_ALREADY_EXISTS如果显卡驱动太旧，就会报错。但是我在 Ubuntu 上用的是新驱动。请看下面：

令人惊讶的是，操作系统使用的PREEMPT_DYNAMIC是 而不是SMP。但是，我没有执行任何内核自定义。因此我预计它是 Ubuntu 中的默认设置，即SMP。请参见下文：
- 内核信息

我正在寻找一些建议来防止我的 Ubuntu 冻结。我想知道设置是否PREEMPT_DYNAMIC是导致此问题的原因。
