Never mind, I found the issue
hw.ata.ata_dma=0
hw.ata.atapi_dma=0
in /boot/loader.conf, hanging around from the days of wood burning power
supplies was causing this strange behaviour! Sorry for the noise folks!

OK, it was a config issue on my part! Some legacy config from the long
ago days of Soekris 5501s, had
hw.ata.ata_dma=0
hw.ata.atapi_dma=0
OK,
Some more odd things going on. If I write to a file from dd some random
junk, not all of the file is saved when I do an unmount. This seems to
be specific either to the ata controller of the APU or to the msata disk
as I tested on a regular server with plain old disks and no issue

I have an APU2. My disk is exactly

I was trying to create a single partition on a 16G mSata drive and
whenever I add a partition, all of a sudden the secondary GPT partion is
borked. Any idea whats going on here ?
0# gpart destroy -F ada0
ada0 destroyed
0# gpart create -s GPT ada0
ada0 created
0# gpart add -t freebsd-ufs ada0
