Hanging on shutdown

When I shutdown/reboot, I see several messages that say "Could not unmount /oldroot/X: Device or resource busy". After that, I see "Storage is finalized." and "Rebooting.", but nothing happens after that.

Screenshot here; apologize in advance for the image quality: https://www.dropbox.com/sc/uupb7ukk9gd2939/opZAOSVG6x

My /etc/fstab is about as minimal as it gets:

# 
# /etc/fstab: static file system information
#
# <file system> <dir>   <type>  <options>       <dump>  <pass>
# /dev/sdb4 LABEL=arch
UUID=3145b7ff-4748-4185-b2e8-4d8b8160178d       /               ext4            rw,relatime,data=ordered        0 1

I have no idea what /oldroot even is. Doing a full system grep, I found a few references to "oldroot" in the stock /lib/initcpio/shutdown script, but that's it.

I'm not really sure where to go from here. Any suggestions?

Re: Hanging on shutdown

I'm having this problem too...sometimes shutdown /reboot hangs forever with those "could not unmount /oldroot/---" messages. I neither know what's the cause.
I'm using mkinitcpio with only systemd hook.
My fstab has only one entry for my second hd:

UUID=7e7a08a7-1ffc-4d0a-b042-185c36cdbd49   /run/media/federico/DATA         ext4      defaults,noatime,noauto,x-systemd.automount     0      0

I mount my root from grub in rw mode...

Re: Hanging on shutdown

do you have any mounted devices when you shutdown. maybe a samba or nfs drive mounted through different means and not via fstab ? other then that, check logs/dmesg after the hang
