[Krzysztof Kozlowski (krzk)]

Regression tests mostly look okay, except:
1. two non-critical kernel selftests failures on amd64,
2. four non-critical kernel selftests failures on arm64, including BPF failure lp:1955011,
3. one possible arm64 kernel crash or hang,
4. several other more-or-less expected failures (hinted like in other flavours).

Since currently amd64 is important, I am marking as regression-testing-passed.
