系统：
- 5.4.0-39-通用 #43-Ubuntu
- AMD 锐龙 7
- AMD 6600XT
- 32GB 内存
- 华硕 B450 Plus
背景：
我一直在 Fedora 31 中使用 Nvidia 970 运行这个 Ryzen 7 和相同的主板，没有任何问题。当我大约 4 天前购买 AMD 6600XT 时，AMD 不提供 Fedora 驱动程序支持，所以我安装了 Ubuntu 20。这是一个新安装的新安装内核和最新的 AMD 驱动程序。过去 3 天我一直在使用此设置，没有问题。我的猜测是我的问题发生大约需要 3 天。
问题：
我正在使用 Proton 玩一个较旧的游戏，我收到一个系统警报，说我几乎没有硬盘空间。我检查了卷，发现我的 syslog 超过 100GB，concatted 文件超过 45GB。我清除了我的日志以节省空间，并在我回到游戏时查看了我的系统日志文件。我一遍又一遍地看到这个错误。我的系统搅动得越厉害，我得到的就越多：

复制：我可以用任何激活显示的游戏来复制这个，包括不使用 wine 的 Linux 游戏，因此，我不认为这是一个 wine 问题。
编辑：删除了旁注，不相关
问题：
这是可以关闭的已知垃圾邮件还是表明存在更严重问题的东西？钻机似乎运行良好，只需要对系统日志问题进行排序即可。
