I cannot tell if those are new for the architecture (Ubuntu 22.04 + AMD Ryzen)

However, Ubuntu's unsigned 6.3.1 generic mainline kernel is also affected.
So, it might seem like an old problem.

(If you could isolate the exact tests, I could try a bisect.)

Yes, just tested, w commit 42510dffd0e2 these are still present
in fcnal-test.sh output:
