Strangely, the system boots now, but kernel panics as soon as "zfs volinit" is attempted: vdev_geom_open_by_guid:352[1]: Searching by guid [13849114725133984793]. panic: _sx_xlock_hard: recursed on non-recursive sx spa_namespace_lock @ /usr/src/sys/modules/zfs/../../cddl/contrib/opensolaris/uts/common/fs/zfs/zvol.c:877 It also drops me to a debug prompt.
