我有一台新的联想 X1 Yoga，Gen5。这是送给我妻子的礼物，所以我几周前配置了它，然后于 12 月 24 日开始使用它。从那时起，它已经锁定了三次。这似乎不是用户界面锁定，因为当它发生时，它会从我的网络中消失。我再也看不到它访问我的 wifi 路由器了。此外，如果它正在播放音乐（三四次锁定中只有一次），它会停止播放。
机器详细信息： 硬件：ThinkPad X1 Yoga Gen 5，16 Gig Ram，制造日期：2020-11-26，BIOS 已更改以允许 VirtualBox 虚拟化
操作系统：Ubuntu 20.04 LTS，启用全盘加密，内核 5.4.0-58。
冻结详情： 最近的一次死机发生在 12 月 28 日 8:07（所以如果有人想查看 kern.log，你可以看到死机）。电脑从前一天晚上开始就处于休眠状态。我打开盖子，转动电脑以使屏幕方向正确，然后开始输入密码。输入第二个字母后，电脑就死机了。我确认没有网络活动，但确实没有，所以我假设这是另一次硬死机。我使用电源开关重置并重新启动。
之前，在将一些音乐从 Pandora 串流并通过蓝牙输出到扬声器时，电脑出现过死机。声音停止，电脑死机。我想我只是在移动文件和安装软件。尝试配置 VirtualBox 时，又出现了一次死机。
我做了什么： 我已经下载了联想硬件测试套件，创建了一个可启动的 U 盘，启动它并运行了所有测试。所有测试均通过。
我制造了一个memetest86可启动 U 盘并运行两次。它总共敲击内存约 2 小时。未报告任何问题。
我下载并使用了Unigine 基准测试工具再次强调 GPU，这似乎有效。我运行了大约 10 分钟。
我使用 VLC 连续 12 个小时播放 YouTube 和 Pandora，同时播放大量文件，没有任何问题。
您如何提供帮助 - 请:-) :
我附上了 kern.log 文件的一部分，该文件记录了 12 月 28 日 08:07:50 时发生的最新崩溃，以便让了解情况的人检查。最终，我想确定这是否是软件问题，或者我是否必须将这台电脑送回。我还保存了整个 /var/log 目录，以防需要其他信息。我必须在 1 月 15 日之前将这台电脑送回，这样在我“拥有它”之前，我还有一些时间可以解决这个问题。
