I saw this on 12.0-CURRENT amd64, at 328401. Steps to reproduce:
$ svn co https://svn.freebsd.org/base/projects/zfsd/head
$ cd head
$ mtree -deU -f etc/mtree/BSD.tests.dist
$ cd tests/sys/cddl
$ make && sudo make install
$ # Now write kyua.conf. Modify as appropriate for your system
$ echo >> /usr/local/etc/kyua/kyua.conf <HERE
-- $FreeBSD$
--
-- System-wide configuration file for kyua(1). See kyua.conf(5) for details
-- on the syntax.
--
syntax(2)
-- User to drop privileges to when invoking kyua(1) as root and a test case
-- requests to be run with non-root permissions.
unprivileged_user = 'tests'
-- An example to set a configuration property specific to FreeBSD.
test_suites.FreeBSD.disks="/dev/da1 /dev/da2 /dev/da3 /dev/da4 /dev/da5
/dev/da6"
test_suites.FreeBSD.keep_pools="zroot tank"
HERE
$ cd /usr/tests/sys/cddl/zfs/tests/cli_root/zpool_upgrade
$ sudo kyua debug zpool_upgrade_test:zpool_upgrade_007_pos
