Subject: XZ compressed kernel broken?

I could not get kernel 4.17 or up to boot on my laptop. I tried various
things, started a new config from scratch on a freshly downloaded (not
up-patched) source tree, to no avail.

Today I tried switching kernel compression from XZ to GZIP and now it
boots fine.

Just as a PSA if your kernel just insta-resets after being loaded from
grub.

Might be some kind of freak interdependency, didn't analyze further.
