That's a pretty old memtest86+. Also, memtest86+ prefers
linuxbios/coreboot memory map to e820. This becomes a problem
when SeaBIOS sets up a USB controller to DMA to e820-reserved
memory that wasn't reserved by coreboot.
Try a modern memtest86+ with the coreboot table probe patched out.

Yep, that was it. Didn't catch the obsolete version number.
I'm trying to figure out the point of memtest86 reading the coreboot
tables. It doesn't help that the coreboot tables / e820 map are
apparently wrong; memtest86+ almost immediately started stepping on the
lower MMIO regions (e.g. 0xb800) rendering the display mostly useless.
Interestingly Linux doesn't seem to have any problems; I'll need to
investigate further.
