GEOM_PART_GPT cannot be nested.
You should backup your data and recreate your partitions, then restore the data.

The hackish way: you can remove GEOM_PART_MBR and GEOM_PART_EBR from your kernel config,
and use GEOM_MBR instead. But you can still use GEOM_PART_GPT. In this case GEOM_PART_GPT will be
attached to the GEOM_MBR provider and nesting will not be detected.
