did a test on a hp 8200 elite sff (i5-2400, 8gb, nvidia quadro 600)
gui screen shows blue background, lubuntu (logo) and dots (normal plymouth) text screen shows
[ 99.999999] ehci-pci 0000:00:1d.0:dma_direct_map_sg: overflow 0x0000000223ad7000+2048 of device mask ffffffff
scrolling by endlessly... (till I rebooted at ~1650.999999 timestamp message)
alas lubuntu 18.10 x86 image was maybe 2 days old.. I updated image to latest, same result (but I didn't wait as long)
