我的 Dell 755 PC 安装了 16.04（和 Windows 10 双启动）有问题。它在一些需要重新启动才能完成的更新后立即启动。
我的问题是，考虑到以下症状，这是否是可报告的错误？如果是，报告中应该包含哪些内容？
当然，我也欢迎有关诊断和修复我的系统的建议。
症状：
- 如果我启动 GRUB 菜单的默认 Ubuntu 选项，它会在检查或修复 sda3 上丢失的 inode 后挂起很长时间，并最终重新启动进入紧急模式。
- 如果我启动到 GRUB 中“高级”子菜单中的“upstart”选项，它可以正常启动。
- 有一次我
journalctl -xb在问题发生期间执行了命令，它显示我的系统磁盘 (sda3) 已超时。成功启动后，该命令什么也没显示。 - PC 可以正常启动 Windows 10。（这是双重启动）。PC 可以正常启动 16.04 版的 Live DVD，并且可以无错误地安装驱动器。
- GSmartControl 没有显示新错误，并且运行测试也没有错误。
诊断/配置信息，根据第一条评论：
sda3、sda5 和 sda6 都是同一主分区上的逻辑分区，该主分区大致从硬盘的“中间”开始，位于 Windows 10 分区之后。
除了 systemd 超时之外，我没有理由认为驱动器出现故障。一旦启动，无论是在 Ubuntu 还是 Win10 中，都没有硬件错误或奇怪的症状。
