Paul, thanks for answering.
Sorry for coming back this late, I was not on the -questions mailinglist,
but found your reply in the archives.

At the time during installation, I did not try to customise any setup
configuration. I just selected auto partitioning with zfs-on-root. This
is the result.

For me it prints:
"""
=> 34 500118125 ada0 GPT (238G)
34 1024 1 freebsd-boot (512K)
1058 4194304 2 freebsd-zfs (2.0G)
4195362 16777216 3 freebsd-swap (8.0G)
20972578 479145581 4 freebsd-zfs (228G)
"""
I use ZFS encryption. Maybe this explains the additional partition.?

I also did that, but it did not change the behaviour. The message is
still popping before the boot menu is shown. Still "Partition table
invalid!"
