It seems as if the logs end before what is shown on the poweroff screen is written to the logs, so i’m guessing the kernel? is hanging at shutdown or reboot? The poweroff screen does show “reached target shutdown” or “reached target poweroff” or something similar but apparently this is not written to the logs for some reason
It also seems to happen more often if I alternate between shutdown or reboot, like if I first shutdown then reboot then shutdown then reboot and so on
I do get kernel soft lockup messages at shutdown and reboot on debian on the power off screen when this happens so I guess the same thing is happening here.
