The ISO doesn't boot on those machines, so I can't get to a terminal.

Done

Walter, thanks again!

I'll have to learn a little about EHCI so I can recognize it.

As for xubuntu x86 daily ISO - I wrote one yesterday to test, but never got 
around to it
I booted it on dell 755 (next to me as I type this), and

"ehci-pci 000:00:1a.7: dma_direct_map_sg: overflow
0x0000000016ca56000+2048 of device mask ffffffff"

(typed, so may not be exact).  It did't continue endlessly, eventually
getting to BusyBox.

I only left one (lubuntu 18.10 image) system go for 30 mins (can't
recall which; both use same keyd/mouse/screen), so maybe a lubuntu image
will also drop to busybox if you want me to try...

I'll add more when I can..
