我正在跟进https://wiki.ubuntu.com/DebuggingKernelSuspend它说我必须重新启动系统
sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend"
hash matches并在重启后在 dmesg 中找到显示的行（这是什么意思？）
嗯，我发现了两个：
[ 3.583591] ima: Allocated hash algorithm: sha1
[ 3.593050] input: AT Raw Set 2 keyboard as /devices/platform/i8042/serio0/input/input4

[ 3.639073] rtc_cmos 00:01: setting system clock to 2016-01-01 12:09:51 UTC (1451650191)
看起来问题出在这两个 acpi 设备上。文章没有说明在这种情况下该怎么做。如果问题出在 PCIe 设备上，我可以简单地卸载其模块，但在这种情况下我该怎么办？acpi 设备有模块吗？如果有，如何找到它的模块？哈希匹配是什么意思？

更新：
wifi/以太网有问题？没有
你的电池/电源运行正常吗？非常好
您是否连接了外部 USB 设备？没有
你有没有注意到其他问题？什么都没有
你的 BIOS 有更新吗？我要安装 Windows 并检查，这需要一段时间
答案1
问题是什么？
输出中有一行dmesg非常引人注目。即：
[ 2.543596] acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM
主动状态电源管理或高级物理治疗师是挂起过程所依赖的省电功能所必需的。此问题已报告这里. 以下引文来自发射台几乎就是您需要知道的内容。
当内核运行固件中的根 PCI 桥 _OSC 控制方法时，会出现此错误消息，并且执行失败，这可能是由于固件中的错误或可能不存在。因此，内核无法确定设备支持的功能或提供的功能（由固件指定），因此必须禁用 PCIe ASPM（活动状态电源管理）。
不启用主动状态电源管理的缺点是机器的电源效率较低，但是，可以使用内核启动参数“pcie_aspm=force”强制启用此功能，但强制启用此功能可能会导致系统锁定。
您为什么会遇到这个问题？
您的笔记本电脑似乎是为使用 Windows 操作系统而制造的，尽管 Ubuntu 和其他 Linux 发行版会模仿 Windows 操作系统对 BIOS 的调用，但有时此交易在另一端会失败，从而发生此类问题。
由此引起的问题可能包括暂停问题、WiFi、以太网、电池、硬盘、SSD 等。因此，我在上面发表了评论：
您的 wifi/以太网有问题吗？您的电池/电源是否正常？您是否连接了外部 USB 设备？您是否注意到其他问题？
其中一些问题在某些 Linux 内核中出现，而在其他内核中消失。它们可能有所不同，但除非系统 BIOS 和内核之间的通信得到修复，否则不太可能完全消失。理想的修复方法是更新 BIOS 来解决 ASPM。
如何解决这个问题？
我建议按以下顺序采取以下解决方案，直到解决此问题：
- 将你的 Ubuntu 更新到较新的版本。较新的内核可能对你的 BIOS 有更好的支持。
- 更新您的 BIOS。较新的 BIOS 版本可能能够更好地与您的操作系统进行通信。
- 在 GRUB 启动菜单中按e并尝试内核启动参数
pcie_aspm=force。请参阅这个答案关于如何添加启动参数。

我的系统有一个 Intel Thunderbolt 控制器，与您的一个 acpi 匹配相同：
