Public bug reported:
硬件型号：Dell Latitude 5590
系统版本：Ubuntu 25.10
内核版本：6.17.0-14-generic
问题描述：
执行 systemctl suspend、合盖后或按下 Super+L时，系统进入睡眠（效果类似于 shutdown -H
now），黑屏且无法唤醒，只能长按电源键强制重启。
已尝试的修复措施：
更新 BIOS 到最新版本（通过 Dell 官网下载的 .rcv 文件更新）。
在GRUB内核参数中添加：
acpi_sleep=s3_mode acpi_sleep=s3_bios acpi_osi=Linux acpi_osi="!Windows 2020"
确认系统支持S3,cat /sys/power/state 输出包含 mem
larry-li@larry-li-Latitude-5590:~$ cat /sys/power/state
freeze mem
larry-li@larry-li-Latitude-5590:~$
附加信息：
该问题在同一电脑 Ubuntu 24.04、Ubuntu 25.10，内核 6.14或6.17上均存在，可能与 ACPI
实现有关，另外这台电脑是通过Ubuntu的启动盘装的系统，预装Windows 10，但已被Ubuntu替代。
相关日志已通过 ubuntu-bug linux 自动收集并附加。
