This reminds me of (otherwise unrelated) problems I had involving Linux 4.15.
If you feel out of ideas, I suggest you take a look at the kernels. It might be that Ubuntu is turning some security-related knob in a different direction than Debian. Or it might be some bug in 4.15 (I found it to be quite buggy, specially during the first few point releases; 4.15 was the first upstream
release including large amounts of meltdown/spectre-related work).
