我最近将 PC 上的 Ubuntu 16.04 升级到了 18.04（配备 Nvidia GeForce GTX 1080 Ti GPU），从那时起我的文件系统就一直在从这些巨大的日志文件中构建。每次我关闭电脑时，我都会收到无数的 pcieport 消息，直到 PC 自行关闭。
昨天晚上我让机器一直开着，当我回来时，出现了一个通知，说磁盘空间已全部用完，也就是说/dev/sda1使用了 100%。我设法通过 -command 发现了这个问题du，并将问题定位到/var/log/-folder 中的日志文件，其中包含超过350GB.
目前，日志文件正在再次累积，现在它们占用的空间约为150GB。导致问题的日志文件是：syslog.1, syslog和kern.log
我的问题是：是什么导致了这个问题以及如何解决它？
我在下面列出了有关我的系统的信息和日志文件中的几行。我会再次删除它们，但无休止地删除它们似乎不是最好的长期解决方案。

答案1
我已经按照此处的说明解决了这个问题（我认为）：
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1521173
解决方法：将 pci=noaer 添加到内核命令行：
（1）编辑 /etc/default/grub，并将 pci=noaer 添加到以 GRUB_CMDLINE_LINUX_DEFAULT 开头的行。它将看起来像这样：
GRUB_CMDLINE_LINUX_DEFAULT="安静启动 pci=noaer"
（2）运行“sudo update-grub”
（3）重启
执行这些步骤之后，关闭系统后我不再收到pcieport消息，并且日志文件的大小也停止大幅增长。
但是，我不知道这是否解决了错误消息的根本原因......
