Assistance is requested to resolve slow shutdown and reboot errors with a fresh installation of openSUSE 15.1 (BTRFS) running KDE on a (low power) desktop machine (HP EliteDesk 800 SFF/83E1, BIOS Q01 Ver. 02.07.01 04/23/2019) with EFI boot from an NVMe SSD. MS OS is not installed.
At ‘Shutdown’ the system hangs at ‘Reached target shutdown’ for 1-2 minutes, then shuts down. It can then be restarted normally. At ‘Reboot’ the system hangs at ‘Reached target shutdown’ for 1-2 minutes, then shows a blank screen for 1-2 minutes, then reboots to a normal looking KDE login screen that is non functional (no response to mouse or keyboard). It can then be restarted normally, after a hard reset.
I suspect these errors may be related to mounting or identifying Swap or perhaps to lvm2 services, installed automaticaly. Logs are not immediatly helpful or not understood. I have found some similar issues reported here but nothing simple enough for me to pursue. I have reached the point where my unskilled attempts to resolve these errors now risks compounding them.

Yast services manager shows lvm2-lvmetad and lvme2-monitor running. LVM is not used.
I trust some of this may be useful.
