I’ve seen the failed to umount /oldroot etc before, my issue with the message (I don’t have the boot delay) is solved by adding shutdown to /etc/mkinitcpio.conf. It probably is one of the solutions you run into when searching for the error. The xhdi_hdc error might be worth exploring further for. That seems to stop the halt process.
Some more old links that might be pointers to solutions.
It seems that showdown issues are not that common as say startup issues and even less solved/posted about.

Last time I looked into this issue (last year) it was something that should have been fixed in systemd 246 (I remember of an issue on github and the “milestone 246” had been added to it iirc).

Tested video recording on a Lenovo G560 with the native webcam driver provided by the distro & there are no shutdown issues. My guess it has something to do with drivers installed after the initial installation causing the issue…
