如果我在列出外部驱动器目录时多次按下 Tab 键，则似乎会出现问题。下面是发生的情况的说明。在控制台 1 中，我尝试列出较低目录的内容，并多次按下 Tab 键以获取下一目录级别的列表。控制台冻结了。如果我打开一个新控制台并尝试列出 media/john，它会冻结。如果我打开第三个控制台并使用 strace，则输出如下。它在第二个 strace 命令上冻结。strace 输出已减少为仅显示第一行和最后一行中的几行。
还有一件事。这种情况以前经常发生，我会重新刷新（NVidia Xavier）以降低频率。但我读到如果更换外部硬盘的电缆，那会有所帮助。所以，我更换了电缆，更换了硬盘，并添加了一个有源（插入式）USB 3.0 集线器来连接硬盘。所以，这个问题现在不经常发生。现在，我通常会进行软重启才能继续。
这是当前问题的详细信息。
