This patch set has no aim to fix those issues but I do believe that it should improve also that feature. If I don't get soon patch reviews for the patch set, I'll pick the 2nd best option: disable bus encryption on all architectures including x86 and ARM64 (being by default on). It's a force majeure situation. I know this would sort out the issue but I really cannot send these as a pull request with zero reviewe-by's. I expect this to be closed by tomorrow. BR, Jarkko
