Fedora 30, pc wont poweroff

Hi,

when I shutdown the pc, screen and fans remain on, the system does not go down until I press the power button.

Reboot the system works well.

If I press “esc” during fedora shutdown splash screen, this is the output:
Imgur

Ho can I troubleshoot and resolve this problem?

You could try the journalctl --system command to review your system logs add a -r to get it in reverse order (newest first).

device-mapper: remove ioctl on fedora-root failed: Device or resource busy

Try to wait for ~10-20 minutes and see if there’s any change.

yeah, after a while the pc shuts down.
How can I understand the problem?

This is an example of my journalctl, nothing interesting, maybe because Journal stops before the poweroff

$ sudo journalctl -b -1 -r

@tonetonetone there is a bug that existed in Fedora 28, but was newer solved.

Here is a link referring to the bug you have
https://bugzilla.redhat.com/show_bug.cgi?id=1402073

I have the same messages when shutting down Fedora 30, but the shutdown newer hangs, the messages appear and the PC turns itself off.

Hello @tonetonetone,
Could you try to shut down the system from a terminal with systemctl poweroff instead of the power down icon? I’m curious if you get to any erro output from systemctl.

I launched systemctl poweroff, but i cannot see any output, it switch imediately to the shut down screen (plymouth).

Hello @tonetonetone,
Perhaps if you open a terminal and use the following command journalctl --system -S today to review your system journal for today, you could find an error or errors that point to what is going on.
