r324353: boot failure: failed with error 19

I run a small appliance on an APU from PCengines. This box is bootet via SD card, the
image is created by a modified NanoBSD, which creates GPT/UEFI partitioning and booting
images.

That worked until two days ago (I do not track the revision numer) when I wrote (via dd)
the last image out. Today, I tried to boot r324353 and it fails at tthe boot loader:


mountroot: waiting for device /dev/ufs/dsks1a...
Mounting from ufs:/dev/ufs/dsks1a failed with error 19.


I can proceed by manually issuing at the loader propmpt

ufs:/dev/gpt/dsks1a

and booting proceeds as expected.  


Something seems wrong with the UFS labeling lately.

The gpt layout looks like this:

gpart show -l:

From dmesg. I can provide this last output:

Can someone look into this?
