从挂起恢复到 RAM 后内核 ATA 异常

从挂起恢复到 RAM 后，我的 Arch Linux 系统冻结并永久无响应。但是，我设法提取以下内核日志：

有问题的存储设备是：

中的所有暂停调试模式/sys/power/pm_test，即freezer、devices、platform、processors、core都不会冻结系统，也不会产生这些错误消息。仅当系统在某个时间后挂起时

# echo none > /sys/power/pm_test

禁用测试挂起到 RAM 时会发生错误。

该错误是什么意思以及我可以采取什么措施来修复它？

编辑：该问题与文件系统或磁盘故障无关：

我有一个奇怪的错误，就像 WD 鱼子酱黑人特有的那样：

请参阅此处的内核错误报告：

https://bugzilla.kernel.org/show_bug.cgi?id=91921

当我有时间的时候，我需要 git bisect 它，因为它似乎是由内核 3.13 中的一些提交引起的。它在内核 3.12 及以下版本中工作。

尝试这个：

回声 0 > /sys/power/pm_async

然后尝试s2ram
