First I attributed it to maybe a bug in meta-mode/ccache + ino64 (easy assumption without knowing if ino64 is involved in zfsloader), but after ccache -C, removing /usr/obj and running 2x "make cleanworld" and 2x "make clean" before a buildworld I now get some kind of a loader-dump (BTX halted) message. The zfsloader binary from a downloaded release-snapshot (r318945) after ino64 update doesn't exhibit this issue.

note, with zfsboot.nok, selecting old kernel and boot did result in nice BTX dump. And pressing the key with default kernel does get reboot.

anyhow, it seems the issue is indeed about compile flags, with all defaults my zfsloader has no problem booting the kernel.
