It is super-easy to reproduce here at least. I tried 18.04 with the ubuntu and the xubuntu CD. Chose default options, except for wanting LVM (and a Danish keyboard).
System gets created fine. At all boots after that, it shows "WARNING:Failed to connect to lvmetad. Falling back to device scanning." at the beginning of the boot process, and then after approx 30 seconds: "Gave up waiting for suspend/resume device /dev/mapper/xubuntu--vg-root: clean XXX/XXX files, XXX/XXX blocks"
