我查看了日志并看到了以下内容：
如果我理解这一点，系统是否会尝试交换到加密交换文件？我的硬盘已加密，并且我设置了一个常规交换文件...

# that works even if disks are added and removed. See fstab(5).

我刚刚又遇到了一次随机冻结（第一次冻结后 7 天），因此我不得不重置我的笔记本电脑，并出现以下日志：

添加 /etc/crypttab：
nvme0n1p3_crypt UUID=bca86e55-cc12-4b54-ba1e-61856cc8db55 none luks,discard
cryptswap /cryptswap /dev/urandom swap
答案1
去除
/dev/mapper/vgubuntu-swap_1 none swap sw 0 0
行来自/etc/fstab。它设置了一个可能不存在的加密交换。
答案2
由于我的交换未加密，因此我删除了以下行：
cryptswap /cryptswap /dev/urandom 从 /etc/crypttab 文件中交换。
