See: #48828 (comment)

I ran the following:

env -i nix-build nixos/release.nix -A tests.boot-stage1.x86_64-linux

Both with linuxPackages set to 4_19 (current default) and 4_20 (to make sure the other change is good).

The patch is literally the one from @aszlig's comment in the linked thread, but applied as a commit on top of the linux repository; only to get it as a fetchpatch-able artifact. Though I do encourage you to load up and verify the patch.

There is no upstream issue opened yet. I don't think I'm able to work with upstream as I don't really know the details of the issue. @aszlig maybe will handle that.
