I see, and I agree that this is frustrating when trying to pinpoint a bug in the 64-bit kernel. On the other hand this is of course a sensible decision, since users clearly should not actually run the 32-bit kernel in this hardware other than for testing purposes. I suppose this is made worse by the lack of a 64-bit kernel option in the armhf installer, which means one has to go through a couple of extra steps to install the arm64 kernel and get a booting system.
