Checkway POS ChwaySH-J安装OpenSUSE 15.6后无法重启问题求助

大家好，想请教个棘手的问题：我在Checkway POS的ChwaySH-J设备上全新安装了OpenSUSE 15.6，结果现在系统重启的时候会直接卡住，完全没反应。

这里有个有意思的细节：在系统安装完成之前，我从安装U盘的菜单里选“退出”或者“重启”选项，设备是能正常重启的，但等系统装完之后，再重启就彻底不行了。

我自己先做了一些排查：

• 把grub启动参数里的splash=silent和quiet去掉了，重启时屏幕最后停在这几行输出：

Reached target System Shutdown
Reached target Late Shutdown Service
Finished System Reboot
Reached target System Reboot

• 为了保留日志排查，给journald加了Storage=persistent配置，下面是journalctl -b -1的末尾部分内容：

systemd[1537]: Stopped target Main User Target.
systemd[1537]: Stopped target Basic System.
systemd[1537]: Stopped target Paths.
systemd[1537]: Stopped target Sockets.
systemd[1537]: Stopped target Timers.
systemd[1537]: Stopped Daily Cleanup of User's Temporary Directories.
systemd[1537]: Closed D-Bus User Message Bus Socket.
systemd[1537]: Stopped Create User Files and Directories.
systemd[1537]: Removed slice User Slice of UID 1000.
systemd[1537]: Reached target Shutdown.
systemd[1]: Reached target Shutdown.
systemd[1]: Starting System Reboot...
systemd[1]: Finished System Reboot.
systemd[1]: Reached target System Reboot.

有没有朋友遇到过类似的硬件+系统的重启兼容问题？或者能给点排查方向的建议？比如是不是ACPI相关的设置需要调整？或者grub里得加什么特殊的重启参数？麻烦大家支支招，谢谢了！
