Errors during shutdown (systemd, Arch Linux, Intel).

Hello everyone, I encountered an issue while trying to shut down my laptop (on top of which runs Arch Linux with the current latest version of systemd (245.6-8)). I also installed and configured plymouth from the AUR (I don't think this is what gave this issue, cause in the beginning it seemed to be working alright). In the last couple of days I set up KVM on Arch Linux (host) and I installed many other programs, therefore I can't say for sure that this is a KVM-related issue. I guess it has to do with my Arch Linux configuration.

What is the problem:
At shutdown some error messages are displayed (if I press ESC immediately after the plymouth logo shows).
If the hook "shutdown" is present, the picture of the logs is the one where ioctl cannot be removed.

If I remove the hook "shutdown" from my mkinitcpio.conf (and I issue "sudo mkinitcpio -p linux"), the message looks slightly different (other picture).

In any case the computer shuts down just fine.

My systemd-boot configuration file looks like this:

title Arch Linux Kernel
linux /vmlinuz-linux
initrd /intel-ucode.img
initrd initramfs-linux.img

options cryptdevice=UUID=[my UUID number]:ArchPad root=/dev/mapper/ArchPad-root quite splash rw loglevel=3 rd.udev.log_priority=3 rd.systemd.show_status=false systemd.show_status=false vt.global_cursor_default=0 net.ipv4.tcp_ecn=0 intel_iommu=on plymouth.enable=1

Please help me find out the cause of these messages at shutdown
