In fact, I'v just started using ZFS recently and I've not updates my working tree since then,
so zfsboot and zfsloader were built using same sources, amd64 stable/11 r322531.

My previous debugging (using added printf's) shows that's zio_checksum_verify()
from src/sys/cddl/boot/zfs/zfssubr.c always fails when zfsloader reads ZFS.
Meantime, zpool scrub finds no errors on this pool when I boot using USB flash/UFS.

I've just added LOADER_NO_GELI_SUPPORT= to my /etc/src.conf, reverted all local
(debugging) changes to /usr/src/sys/boot, did "make clean all install" there
and tried to boot using rebuilt zfsloader again (it it 44KB less now than zfsloader.old).
No changes, still fails same way. And I do not have r326583.
