Hanging on reboot with black screen and blinking underscore

Question

Everything works, but when I reboot via "systemctl reboot" or through GNOME, it will never actually reboot, but instead it gets stuck in a black screen with blinking underscore cursor, and I am forced to do a hard-reset.

These are the last entries in the journalctl -r:

Mar 14 23:07:29 Desktop systemd-journald[417]: Journal stopped
Mar 14 23:07:29 Desktop systemd-shutdown[1]: Sending SIGTERM to remaining processes...

Mar 14 23:07:29 Desktop systemd[1]: Reached target Shutdown.
Mar 14 23:07:29 Desktop systemd[1]: Removed slice system-systemd\x2dfsck.slice.

Any idea why this is happening?

EDIT: It seems that it actually does reboot after exactly 2 minutes each time. So I think it may be waiting for some process to end? This happens every time though, even when rebooting right after booting into the DM. Could be X11 related?

Here is the journalctl -r:

Mar 16 20:53:23 Desktop kernel: Linux version 5.0.2-arch1-1-ARCH (builduser@heftig-15298) (gcc version 8.2.1 20181127 (GCC)) #1 SMP PREEMPT Thu Mar 14 18:47:49 UTC 2019
-- Reboot --
Mar 16 20:51:24 Desktop systemd-journald[419]: Journal stopped

Solution

I was having the same problem, I fixed it by changing

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"

in

/etc/default/grub

and then running

# grub-mkconfig -o /boot/grub/grub.cfg

In my case is cause by my bluetooth 5 dongle, if thats the case just unplug dongle during restart.

Unfortunately that did not work. I did, however, go through all combinations of "reboot=pci" and "reboot=b", etc, but to no avail. I edited the original post. It seems that it is actually booting, but it takes 2 minutes. Maybe it's waiting for some weird process to finish? I cannot find any info on this

yeah the last msg is "Target reached Reboot"
