异常 Emask 0x10 SAct 0x0 SErr 0x4060000 操作 0xe 冻结 t2

我在 kern.log 中收到所有这些错误,但我不知道如何调查它们。

我什至不确定哪一个与这个问题的标题最相关。

AFAIU,这可能与硬件有关。但我什至不知道是哪一部分。硬盘?母板?

我移除了所有 USB 设备,断开了 DVD 驱动器的连接,并更换了硬盘驱动器的SATA电缆。我现在只有一个硬盘,带有一根新的(并且已知可以工作)SATA 电缆。

我还用 smartmontools 检查了硬盘:

AFAIU,没有发现问题。

除了那些填充我的日志文件的消息之外,我没有看到任何异常行为。

FWIW,这台机器作为 nvidia 显卡并使用 nouveau (无专有驱动程序)。
