从/向使用任何格式的USB驱动器复制文件时，系统会冻结

我会在这里问这个问题，因为我似乎已经难倒了Linux Mint的人。 我一直在使用Linux Mint一年半。 我有3台电脑，2台在Linux上运行。 我的主电脑是台式电脑塔。 几天前，当我对Mint 18.2感到沮丧时，我将主计算机切换到了UbuntuStudio。 但问题只是略有减少，而且UbuntuStudio没有消失。 这是一个严重的问题。

症状是我无法从任何外部USB驱动器读取或写入文件，而系统不会崩溃并完全冻结。 驱动器可以格式化为NTFS，FAT32或EXT4。 最糟糕的是ext4。 唯一的出路就是硬重启。 （关闭按钮）此问题甚至包括FAT32存储卡。 我可以在系统冻结之前传输一些文件。 但是传输大文件或大量数据文件似乎是不可能的。

此问题仅影响一台计算机。

电脑：

• AMD FX（tm）-4300四核处理器。
• 记忆：16043 MiB。

硬盘驱动器已经关闭。 它确实有3个内部硬盘驱动器，用于5 TB的空间。 主驱动器有1 TB的空间。 我用一个4 TB替换了所有这些驱动器。 驾驶。 由于此问题，驱动器被切换。 （我认为其中一个驱动器可能存在问题。）我还有大约25 TB的存储空间，我通过USB端口插入，包括RAID塔。 所有额外存储都格式化为NTFS。 但是内部的驱动器正在通过外部硬盘驱动器接口读取。 此计算机中没有内置存储卡读卡器。 我使用USB2和USB 3适配器作为存储卡。

在查看日志时，我发现PAM一直在和我签约。 我正在签署“root”和“user”。 当我看到正在传输的文件开始变慢时，如果我查看Auth日志，它将显示我刚刚以用户身份注销。

以下内容来自Auth日志和系统日志。 第一个被复制并保存，因为复制过程正在减慢。 计算机稍后冻结了一秒钟。 （下面的另外2个日志复制/粘贴是从重新启动后的当天记录开始的。）我试着让它静置一个小时，看看它是否可以恢复。 它没用。

此记录是在UbuntuStudio下拍摄的：
