我最近在电脑上安装了 Ubuntu 22.04.2，系统挂起似乎不起作用。我一直在论坛上寻找答案，因为这似乎是一个常见问题，但我找不到与任何解决方案相匹配的明显问题。
具体来说，在运行时systemctl suspend，系统似乎正确进入睡眠状态，但随后立即唤醒。查看日志时dmesg，没有明显的错误，systemctl status suspend.target似乎证实了这一点：
○ suspend.target - Suspend
Loaded: loaded (/lib/systemd/system/suspend.target; static)
Active: inactive (dead)
Docs: man:systemd.special(7)
May 17 09:42:37 systemd[1]: Reached target Suspend.
May 17 09:42:37 systemd[1]: Stopped target Suspend.
以下是dmesgafter的输出systemctl suspend：

我检查了所有我知道的显而易见的东西，我的内存swap比 RAM 多，我的 BIOS 设置在电源管理方面没有任何明确阻止睡眠/挂起的内容，我正在使用 Ubuntu 打包的 AMD 驱动程序，没有任何外围设备的专有驱动程序。
这是一台定制 PC：32 GB RAM（34 GB 交换）、AMD Radeon RX6600、AMD® Ryzen 5 5600X、Gigabyte B550M 主板。
答案1
重新安装后，通过谷歌搜索修复方法，发现此问题在本轮直播中提出。
这很可能是“技嘉 B550 系列主板在 Linux 上无法退出挂起状态” GPP0/GPP8 错误，似乎发生在 NVME SSD 上。我无法诊断，每个错误都变成了一个干扰，直到有人看到我的日志，并且之前已经见过它。我无法退出挂起状态，只能通过掷骰子并在内存失去电量（或任何过程）之前关闭和打开后开关来唤醒。
来自 Reddit 帖子https://www.reddit.com/r/archlinux/comments/11urtla/comment/jg46a0p：
GPP 桥接器是导致此问题的原因，可能是安装了 nvme ssd 时导致的。禁用桥接器的唤醒功能可解决此问题。
https://bbs.archlinux.org/viewtopic.php?id=284401是初步的解决方案，
$ sudo sh -c "echo GPP0 > /proc/acpi/wakeup"
$ sudo sh -c "echo GPP8 > /proc/acpi/wakeup"
https://www.reddit.com/r/archlinux/comments/11urtla/comment/jg46a0p添加一个 systemd 服务，该服务每次启动时都会更改它：
创建一个 systemd 服务在每次启动时执行此操作也是有意义的。创建一个名为 /etc/systemd/system/sleep-workaround.service 的文件，内容如下：
[Unit]
Description=Workaround for Gigabyte B550 AC bios sleep bug
[Service]
ExecStart=/bin/sh -c "echo GPP0 > /proc/acpi/wakeup && echo GPP8 > /proc/acpi/wakeup"
[Install]
WantedBy = multi-user.target
然后使用 [sudo systemctl daemon-reload 和] sudo systemctl enable sleep-workaround 启用该服务。我希望这些信息最终能对某些人有所帮助。
即使已经闲置了 6 个月，也要在这里发布，希望它能引起人们的关注。如果你不知道自己在寻找什么，那么调试起来就很困难。
由于这里未启用 DM，有评论声誉的人能否回复上面的帖子并提醒 @scrollout？他们的问题已被关闭，但这是同一个问题。
