Well, it does seem to happen. My memory stress-tester has been running
for about half an hour now with the revert I posted - it used to
trigger the problem in maybe ~5 minutes before.
So I do think that revert fixes it for me. No guarantees, but since I
figured out how to trigger it, it's been fairly reliable.

I'm attaching the relevant (?) parts of dmesg, which has the node
ranges, maybe you can see what the problem with the code is.
(NOTE! This dmesg is with that "mem=6G" command line option, which causes that
e820: remove [mem 0x180000000-0xfffffffffffffffe] usable
line - that's just because it's my stress-test boot. It happens with
or without it, but without the "mem=6G" it took days to trigger).
I'm more than willing to test patches (either for added information or
for testing fixes), although I think I'm getting off the computer for
today.
