我正在运行带有 3.x 系列内核的 Linux Mint 17。今天我记得推荐的内核升级已经搁置了几周，所以我认为它可能值得升级（在 Mint 中，系统更新根据重要性和稳定性分为 1-5 级，其中 1 是最重要或最稳定的）这些更新是 5)。
此次升级将我的系统从内核 3.13.0-139-generic 迁移到 linux-headers-3.13.0-149-generic。我在 VirtualBox 与窗口管理器交互方面遇到了一些长期存在的小问题，我隐约希望这能解决这些问题。然而，我很快注意到机器无法从睡眠中唤醒。
当我合上笔记本电脑的盖子时，机器似乎成功进入睡眠状态（只要适配器未插入，电源指示灯就会熄灭）。使用新内核时，打开笔记本电脑时，显示屏不会亮起，并且按下 Caps Lock 键不会影响按键上 LED 的状态。简而言之，这看起来像是一次非常严重的崩溃。我必须按住电源按钮关闭系统，然后再打开，才能再次使用机器。
然后，我尝试使用旧内核（通过在启动时按住 Esc，然后从 Grub 菜单中进行选择），这修复了它（暂时，无论如何，直到下一次系统重新启动）。
我想报告这个错误，或者确保它被报告。然而，从我得到的结果来看，搜索“挂起唤醒 Linux Mint 17”和类似的变体似乎不够具体。我希望能够通过找出问题所在（例如查看是否存在硬件驱动程序错误）来进一步确定问题。
我想像 syslog 和 dmesg 这样的东西在这里会有所帮助，但是我没有看到太多看起来像罪魁祸首的东西。这是我的系统日志的一部分，看起来记录了睡眠/唤醒事件：

dmesg 文件也没有看起来所有相关的东西 - 取消挂起是可见的，但没有错误。
为了能够查看错误是否已被记录，我还可以调查哪些其他事情？
（另外，我计划在某个时候升级到 Linux Mint 18.x，这有望解决这个问题，但短期内我可能只是将内核降级到旧的工作内核）。
