Bug Description
-- Background --
Testing the x86 (32bit) ISO image on various machines.
After zsync download, the thumb-drive is tested ("check disk for defects") & passes; and worked fine on two systems today (dell d610 & hp dx6120), however
-- Issue --
dell 755 (desktop) & hp dc7700 (small form factor) it just sits at lubuntu plymouth screen.
switching to messages, it's just the following repeating
// on dell 755
"ehci-pci 0000:00:1a.7: dma_direct_map_sg: overflow 0x000000016e3f3
// on hp dc7700
"ehci-pci 0000:00:1a.7: dma_direct_map_sg: overflow 0x0000000162317
NOTE: I can't copy/paste from systems, as it never completes boot; I left it >30mins (on 755) & it just kept repeating message. I've manually typed it; so typo's could have been made.
A discussion on #lubuntu-devel provided a possible cause (Thank you Walter!) -

<wxl> seems like it's a usb issue of some kind with 4.18

This fits because whilst I do my testing mostly on d610 & t43 (no issues today), I'd tested Lubuntu 18.10 before on the dell 755 with no issues. My last test was also long enough ago to be on 4.17 kernel (suspicion)

[ 99.999999] ehci-pci 0000:00:
errors on booting 'live' (see #16) for real
BUT
the same ISO works fine on same box when a virtual machine (Virtual box on a GNU/Linux host and "Type: Linux Version: Ubuntu (32-bit)" virtual machine)
