Preparing a new r222654 kernel and booting with kern.geom.part.check_integrity=0
didn't cure anything.
See http://people.freebsd.org/~mr/boot_3.txt for a "boot -v" using
 	set kern.geom.label.debug=1
additionaly

But reverting /sys/geom to r221381 allows to boot.
See http://people.freebsd.org/~mr/boot_4.txt for a "boot -s" using
 	set vfs.zfs.debug=1
 	set kern.geom.debugflags=4
 	set kern.geom.label.debug=1
additionaly.

So the problem seems to be related to the recent geom changes...
