问题针对所有暂停/重启/关机，但描述和日志仅针对最后一次暂停。
我无法暂停系统。我暂停了systemctl suspend系统，显示器关闭了，但 CPU 仍在运行。然后我无法再次恢复系统，只能强制关机。nvidia535 和 nouveau 驱动程序都出现过这种情况。

答案1
根据我对 Kernel.org 文档的理解，暂停并不意味着“CPU 停止执行任何工作”。“处理器……大部分时间处于空闲状态”。虽然这可能只是“意味着电源正在轻微地供应给 CPU，但甚至连低级代码都没有被执行”。还值得阅读不同类型的挂起状态的描述，确定您正在进入哪一种状态，并尝试确定这是否可能是导致问题的原因？
另外，值得一看的是，您是否可能误判 CPU 正在运行。您究竟是如何检查这一点的？这是否与我遗漏的日志有关？
作为另一种调试方法，请查看此线，可能是您的sleep.conf文件（如果存在）配置不正确，导致发送了一些/sys/power/state不应该发送的内容。
